27.   The energy (such as light and heat) released by the Sun is produced by nuclear reactions in the core of the Sun, which convert hydrogen into helium. According to Einstein's equation E = mc2, the mass of one helium nucleus should be

(a)   less than the mass of four hydrogen nuclei.
(b)   greater than the mass of four hydrogen nuclei.
(c)   equal to the mass of four hydrogen nuclei, since the energy is unrelated to the masses of hydrogen or helium, but originates in the electromagnetic fields of these atoms.
