The source of energy in nuclear power reactor
A. Nuclear fission reaction
B. Exothermic chemical reaction
C. Nuclear fusion reaction
D. Controlled nuclear fission chain reaction​

Answer 1

Explanation:

All of the energy we produce comes from basic chemical and physical processes.

That’s mostly been accomplished throughout history by burning carbon-based material like wood, coal and gas—or by harnessing power from the sun, wind, and water.

Fission and fusion are two physical processes that produce massive amounts of energy from atoms.

They yield millions of times more energy than other sources through nuclear reactions.
