Solution

The correct option is B $10^{7} K$
Nuclear fusion is possible only at high temperature and pressure. Nearly, a temperature of $10^{7} K$ is required to initiate a nuclear fusion by overcoming the electrostatic repulsion between the nuclei. In a fusion reaction, two lighter nuclei combine to form a heavier nucleus.
