Answer:
Correct Answer: A
Solution:
[a] A fusion reaction between hydrogen nuclei is difficult because positively charged nuclei repel each other. However, at very high temperatures of the order of $ 10^{6} $ to $ 10^{7} $ K, the nuclei may have sufficient energy to overcome the repulsive forces and thus fuse. This is why, fusion reactions are also called thermonuclear reactions.
