'Nuclear Fusion' is the process of combining of two or more light nuclei. What is the required temperature (approximately) for nuclear fusion?

Correct option is A

The correct answer is (A) 100 million K.

Explanation:
Nuclear fusion requires extremely high temperatures, around 100 million K, to enable hydrogen nuclei to overcome electrostatic repulsion and fuse into heavier elements, releasing massive energy. This is the process that powers the Sun and stars.

Information Booster:

• Nuclear fusion occurs in the Sun's core and is being researched for clean energy production.
• 100 million K is needed to overcome the Coulomb barrier, allowing nuclei to fuse.
• The International Thermonuclear Experimental Reactor (ITER) is working on achieving sustainable fusion energy.
