GENERAL KNOWLEDGE

Detailed explanation-1: -In the process of nuclear fusion, some amount of the mass of the hydrogen atoms gets converted into energy that is seen in the form of light. Therefore the reaction that takes place in the sun is nuclear fusion.

Detailed explanation-2: -Nuclear fusion reaction takes place in the Sun. The Sun’s tremendous pressure and high temperature fuse hydrogen nuclei to form helium through various steps.

Detailed explanation-3: -The energy from the Sun-both heat and light energy-originates from a nuclear fusion process that is occurring inside the core of the Sun. The specific type of fusion that occurs inside of the Sun is known as proton-proton fusion.
