Fusion reaction takes place at high temperature because

Fusion reaction takes place at high temperature because
  1. atoms get ionised at high temperature
  2. kinetic energy is high enough to overcome the coulomb repulsion between nuclei
  3. molecules break up at high temperature
  4. nuclei break up at high temperature

Solution

Fusion reaction takes place at high temperature because kinetic energy is high enough to overcome the coulomb repulsion between nuclei.
