Answer 1

Hydrogen and helium atoms fuse together to generate stars. The heat produced by this process releases a lot of energy. Four hydrogen atoms and one helium atom are fused together in this procedure. Thus, the correct option is C.

What is helium?

Hydrogen and helium atoms fuse together to generate stars. The heat produced by this process releases a lot of energy. Four hydrogen atoms and one helium atom are fused together in this procedure. The nuclear fusion processes are caused by the external heat, pressure, and gravitational force. The pressure produced by the heat allows the helium atom to fuse with carbon. These fusions are required to give the star its form.
