Fusion reaction takes place at high temperature because

Options

(a) nuclei break up at high temperature
(b) atoms get ionised at high temperature
(c) kinetic energy is high enough to overcome the coulomb repulsion between nuclei
(d) molecules break up at high temperature

Correct Answer:

kinetic energy is high enough to overcome the coulomb repulsion between nuclei

Explanation:

When the coulomb repulsion between the nuclei is overcome then nuclear fusion reaction takes place. This is possible when temperature is too high.
