Question
Which of the following is the primary reason for the tremendous energy generated from the Sun and the other stars?
Explanation
Sun's core fuses hydrogen nuclei into helium via proton-proton cycle at 15 million Kelvin, converting mass deficit into enormous energy per Einstein's E=mc2. This thermonuclear fusion sustains stellar luminosity and nucleosynthesis across main-sequence lifetimes.
