Which chemical reaction releases the most energy?
a. nuclear chain reaction
b. fission reaction
c. fusion reaction
d. chemical reaction

The answer is C

Nuclear fusion is a process in which two atomic nuclei unite to form a heavier nucleus. Fusion is the natural energy source of the Sun and stars. The fusion of light nuclei generates large amounts of energy, which is the nuclear melting point, which theoretically can produce 3 and 4 times more energy than fusion, the same mass of fuel.

Actually it is "And generations pass, as they have passed" and "thousands of times has the old tale has been told".

Hope it helps homies.
