Which of the following is an example of nuclear fusion ?
- A Formation of \( {}^{144}_{56}Ba \) and \( {}^{89}_{36}Kr \) from \( {}^{235}_{92}U \)
- B Formation of \( {}^{239}_{94}Pu \) from \( {}^{235}_{92}U \)
- C Formation of \( {}^{4}_{2}He \) from \( {}^{2}_{1}H \)
- D Formation of water from hydrogen and oxygen
Answer & Solution
Correct Answer
(C) Formation of \( {}^{4}_{2}He \) from \( {}^{2}_{1}H \)
Step-by-step Solution
Detailed explanation
Nuclear fusion is the process where light nuclei combine to form a heavier nucleus, such as hydrogen isotopes merging to create helium. In contrast, Option A is an example of fission (splitting a nucleus), and Option D is a chemical reaction, not a nuclear one. C) Formation of…
