Energy in the sun is produced by the fusion of four protons into a helium nucleus. The process involves several steps, but the net reaction is simply \(4 \mathrm{p} \rightarrow{ }^{4} \mathrm{He}+\) energy. Given this, you can say that A. One helium atom has more mass than four hydrogen atoms.

B. One helium atom has less mass than four hydrogen atoms.

C. One helium atom has the same mass as four hydrogen atoms.
