Question

Is the principle reaction responsible for the energy output of the sun :

• A. Gamma decay
• B. Nuclear fusion
• C. Alpha decay
• D. Positron emission
• E. Nuclear fission

Answer 1

The correct option is B Nuclear fusion

The fusion of nuclei in a star, starting from its initial hydrogen and helium abundance, provides that energy and synthesizes new nuclei as a byproduct of the fusion process.

The prime energy producer in the Sun is the fusion of hydrogen to form helium, which occurs at a solar-core temperature of 14 million kelvin.

Option-A is correct.
