Which of the following elements is most likely to be produced during a nuclear fusion reaction helium-4 hydrogen-1 uranium-235 or uranium-238?

Helium-4 can be a product of fusion. Hydrogen-1 cannot be produced by fusion. The uranium isotopes were probably produced by fusion in some star, long ago, and possibly not as uranium, but as something that decayed into uranium. I suppose it would be possible to produce the uranium isotopes in a lab by fusion, but I cannot imagine anyone do so, unless it was to prove a point.

What elements contain more than one type of atom?
Most do. They are called isotopes. For a particular element the number of protons in the nucleus is the same, but there can be different numbers of neutrons. For example uranium235 and uranium238 where the number is called the mass number, which is the sum of the numbers of protons and neutrons in the nucleus. Isotopes of hydrogen are specially given individual names (hydrogen, deuterium, tritium) but they are all "chemically" hydrogen (protons=1, electrons=1).
