Fusion could occur with two deuterium nuclei, or one deuterium and one tritium. Helium would be formed in both cases, but does not take part in the fusion itself.
The most likely reaction of deuterium and helium would be:
D + He --> LiM --> D + D + D
The "M" superscript indicates an excited metastable nucleus that instantly breaks apart.
Another reaction is similarly likely:
D + He --> LiM --> D + He
Either way you are making no progress with fusion, the net reaction(s) probably even consumes energy instead of releasing it (my references don't supply energy figures for these reactions). Also such reactions would require higher temperature and pressure than DD or DT fusion do.
Note: deuterium/helium-3 fusion does work and releases energy (at higher temperature and pressure than DD or DT fusion) but only produces helium and neutrons. Helium-3 is also rare.
In practice, the original answer is absolutely right. However the above reactions will happen under conditions of temperature and pressure that permit D/He fusion, but as I already said they get nowhere, they are dead end reactions.

What is a giant ball of gas primarily hydrogen and helium which undergoes nuclear fusion?
Star
What is a red giants core called?
A red giant's core is called a helium core. This is because as a red giant forms, the core of the star contracts and heats up, causing hydrogen fusion to transition to helium fusion.
What are the types of gases in a blue giant?
The main types of gases found in a blue giant star are hydrogen and helium. These stars are very hot and massive, causing the hydrogen and helium to undergo fusion reactions in their cores, releasing vast amounts of energy. Other elements may also be present in smaller quantities due to fusion processes in the star's core.
What process causes the Sun to continually burn?
The sun does not burn in the classical sense. The sun is so massive that, at its center, matter is compressed with such force hard that Hydrogen atoms fuse together to form Helium atoms. This fusion process liberates a great deal of energy, which escapes as light.
How many atoms of hydrogen are needed to create 1 atom of helium?
Four. There are a couple of possible routes to the fusion reaction that makes helium-4 as a finished product, but it's all about the hydrogen. Most hydrogen is just one proton. Helium-4 has two protons and two neutrons. It takes two hydrogen atoms to contribute their two protons to the nucleus of our He-4 atom. And it takes two more hydrogen atoms (the protons) to undergo transformation into two neutrons to complete the assembly. Note that atoms do not exist as such anywhere on or in the sun. The temperatures are far too high for any electrons to be hanging around any nuclei; our star is a ball of plasma. Our friends at Wikipedia have a nice article posted on proton-proton fusion. A link is provided.
Which type of fusion occurs in the red giant phase?
The primary type of fusion that occurs in the red giant phase is helium fusion. As the star's core runs out of hydrogen fuel, it contracts and heats up to the point where helium fusion can begin, converting helium into carbon and oxygen. This process generates energy and causes the star to expand and become a red giant.
What is a giant ball of gas primarily hydrogen and helium which undergoes nuclear fusion?
Star
How nuclear fusion in a main sequence is different from nuclear fusion in a giant star?
Nuclear Fusion in a Giant Star involves Helium being fused into a hydrogen shell that surrounds the core, and Nuclear Fusion in a Main-Sequence star involves Hydrogen being fused into Helium to produce Energy inside of the core.
How is nuclear fusion in a main-sequence star is different from nuclear fusion in a giant star.?
Nuclear Fusion in a Giant Star involves Helium being fused into a hydrogen shell that surrounds the core, and Nuclear Fusion in a Main-Sequence star involves Hydrogen being fused into Helium to produce Energy inside of the core.
The fuel for fusion in the sun's core?
hydrogen atoms join to form helium. no hydrogen= red giant=white dwarf= DEAD
What elements is the fuel for main sequence?
Stars a giant balls of gas mainly hydrogen and helium. inside a star there are such temperatures that hydrogen fusion occurs making helium and when the star runs outta hydrogen it gets hotter and helium fusion occurs then carbon fusion etc etc. so ultimately it depends on the age of the star.
What element is the fuel for main-sequence star?
Stars a giant balls of gas mainly hydrogen and helium. inside a star there are such temperatures that hydrogen fusion occurs making helium and when the star runs outta hydrogen it gets hotter and helium fusion occurs then carbon fusion etc etc. so ultimately it depends on the age of the star.
What is a red giants core called?
A red giant's core is called a helium core. This is because as a red giant forms, the core of the star contracts and heats up, causing hydrogen fusion to transition to helium fusion.
What fuses during the red giant phase?
During the red giant phase, hydrogen fusion occurs in the shell surrounding the helium core. The core is no longer fusing hydrogen, as it has already converted most of its hydrogen into helium. This causes the outer layers of the star to expand and cool, leading to the red giant phase.
What is the process they generates energy into the core of the main sequence star?
Hydrogen fusion to make helium. When a star runs out of hydrogen in its core to fuse, it begins collapsing, leaves the main sequence, then ignites helium fusion to make carbon, becoming a red giant.
What produces sun's energy?
Nuclear fusion of Hydrogen to Helium is what produces the Sun's Energy. this takes place in the core. Later when it becomes a Red Giant it will fuse Helium to Carbon
What ful do stars on the main sequence burn?
it is fusion of hydrogen into helium. (like our sun) if it is a red giant (the next stage of our suns life) it is burning helium into denser things.
