Question:

Which of the following is an example of nuclear fusion?

Options:

Formation of ${_{56}^{144}Ba}$ and ${_{36}^{89}Kr}$ from ${_{92}^{235}U}$

Formation of ${_{94}^{235}Pu}$ from ${_{92}^{235}U}$

Formation of ${_2^4He}$ from ${_1^2H}$

Formation of water from hydrogen and oxygen

Correct Answer:

Formation of ${_2^4He}$ from ${_1^2H}$

Explanation:

The correct answer is Option (3) → Formation of ${_2^4He}$ from ${_1^2H}$

Nuclear fusion is the process in which two lights nuclei combine to form a heavier nucleus, releasing a significant amount of energy.

${_1^2H}+{_1^2H}→{_2^4He}+Energy$
