The fundamental nuclear reaction occurring in the core of the Sun is
A)nuclear fission.
B)radioactive decay.
C)nuclear fusion of hydrogen into helium.
D)nuclear fusion of helium to carbon.

Question

Quizplus · Accepted Answer

The fundamental nuclear reaction occurring in the core of the Sun is the fusion of hydrogen nuclei (protons) into helium. This process releases an enormous amount of energy in the form of heat and light, which is what sustains the Sun's energy output over its lifetime. Fission and radioactive decay are not relevant to the Sun's energy production, and the fusion of helium is not the primary reaction occurring in the core of the Sun.
