Which of the following is not an advantage of using a fusion reaction instead of a fission reaction to produce energy? a) workers are not in as much danger from radiation. b) hydrogen is used, and hydrogen is easily obtained from water. c) no harmful waste products are produced. d) fusion reactors require less energy than fission reactors do.

Option (D) is the correct answer.

Explanation:

A fusion reaction is a reaction in which two small nuclei combine together to form a larger nuclei. Whereas in fission reaction, a heavier nucleus divides into lighter or small nuclei.

Fission reaction occurs due to absorption of energy whereas fusion reaction occurs due to the release of energy.

Fission reaction produces much more energy as compared to fusion reactions.

Thus, we can conclude that fusion reactors require less energy than fission reactors do is NOT an advantage of using a fusion reaction instead of a fission reaction to produce energy.
