GENERAL KNOWLEDGE

Detailed explanation-1: -Nuclear Fusion reactions power the Sun and other stars. In a fusion reaction, two light nuclei merge to form a single heavier nucleus. The process releases energy because the total mass of the resulting single nucleus is less than the mass of the two original nuclei.

Detailed explanation-2: -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.

Detailed explanation-3: -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-4: -Nuclear fusion is what happens in the Sun and other stars and involves joining two atomic nuclei to make one larger one. Both reactions release large amounts of energy, but with nuclear fusion there is very high energy yield and very low nuclear waste production.

Detailed explanation-5: -During nuclear fission, a neutron collides with a uranium atom and splits it, releasing a large amount of energy in the form of heat and radiation. More neutrons are also released when a uranium atom splits. These neutrons continue to collide with other uranium atoms, and the process repeats itself over and over again.
