Which of these develop when gravity pulls gas and dust together with enough pressure to ignite nuclear fission?

The list of choices posted with the question doesn't include anything
that fits that description.
It sounds something like a "star", but in a star, it would be "fusion", not "fission".

Why a fission reaction is neccasary for fusion reaction?
It isn't, in general. Thermonuclear bombs use a fission bomb to generate the heat and pressure required to start the fusion process, but there are other ways of doing it (stars do so by gravity, for instance).
What two forces are at work in a star?
In actual stars, all four fundamental forces (strong, weak, electromagnetic, gravity) are at work.
What causes pressure in fluid's?
All of the forces exerted by the individual molecules in a fluid add together to make up the pressure exerted by the fluid
Does air pressure affect gravity?
Gravity is a function of mass and distance. So, no air pressure does not affect gravity.
What effect does gravity have on stars?
Gravity pulls gas particle together. As gravity pulls more and more atoms, closer and closer together they eventually begin to fuse together. Once fusion starts on a large enough scale, at star is born.
Is there anything inside the earth to balance the gravitational force?
Yes, the pressure of the materials that are pressed together by gravity.Yes, the pressure of the materials that are pressed together by gravity.Yes, the pressure of the materials that are pressed together by gravity.Yes, the pressure of the materials that are pressed together by gravity.
Is a nebula held together of the outward force of gravity?
No an nebula is held together by the balance of the inward force of gravity and outward pressure.
Is there a balance between pressure and gravity in main sequence stars?
Gravity is constantly pulling the matter of a star together, while the nuclear fission reaction that makes the star shine and put off heat is trying to make it explode. The two are very precariously balanced.
Which of these develop when gravity pulls gas and dust together with enough pressure to ignite nuclear fusion?
Having some trouble seeing your list of choices from here.But stars do.
What two factors cause a nebula to develop into a star?
The two main factors that cause a nebula to develop into a star are gravity and heat. Gravity pulls the gas and dust in the nebula together, causing it to collapse under its own gravity. As the collapse continues, the temperature and pressure in the core of the collapsing nebula increase, eventually reaching a point where nuclear fusion ignites, and a star is born.

How do gravity and pressure keep a nebula from collapsing?
the pressure pushes the nebula together just like magnets to keep it from falling or collapsing, and the gravity pulls the exess debri into the nebula to keep it packed tight.
Are stars born when gravity pulls gas and dust together with enough pressure to ignite nuclear fusion?
Yes, stars are born when gravity pulls gas and dust together from a nebula.
Stars are formed from interstellar clouds because of?
Because of gravity. Only gravity can pull large clouds together with enough force to overcome gas pressure.
How does specific gravity effect head pressure?
Head pressure=specific gravity*1000*gravity*height. Therefore if specific gravity is increased head pressure will increase.
What causes pressure in fluid's?
All of the forces exerted by the individual molecules in a fluid add together to make up the pressure exerted by the fluid
