SOLAR SYSTEM

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. So, the correct answer is “Option B”.

Detailed explanation-2: -The specific type of fusion that occurs inside of the Sun is known as proton-proton fusion. Inside the Sun, this process begins with protons (which is simply a lone hydrogen nucleus) and through a series of steps, these protons fuse together and are turned into helium.

Detailed explanation-3: -In the core of the Sun hydrogen is being converted into helium. This is called nuclear fusion. It takes four hydrogen atoms to fuse into each helium atom.

Detailed explanation-4: -Fusion occurs when two atoms slam together to form a heavier atom, like when two hydrogen atoms fuse to form one helium atom. This is the same process that powers the sun and creates huge amounts of energy-several times greater than fission.
