Why the Fusion reaction takes place at high temperature among the nuclei, though these experience repulsion between them:

atoms get ionised at high temperatures Molecule breakup at high temperate Kinetic energy is high enough to overcome repulsion between nuclei Nuclei break at high temperature and is independent of repulsion between nuclei at this is temperature

Kinetic energy is high enough to overcome repulsion between nuclei

The correct answer is Option (3) → Kinetic energy is high enough to overcome repulsion between nuclei
