Solution

The correct option is D Nuclear fusion
In nuclear fusion, two small nuclei come close to each other and fuse to form one bigger nucleus at very high temperatures. The energy of sun is generated mainly by the nuclear fusion of hydrogen nucleus into helium. Fusion is the primary process because of abundance of Hydrogen and high temperature.
