Answer: The correct answer is C) They both have a high energy output.
Fusion is a thermo nuclear process in which two light nuclei combine to form a heavy stable nucleus with the release of high amount of energy.
For instance, formation of stars.
On the other hand, fission is thermonuclear reaction in which a heavy unstable nucleus is broken down into light stable nuclei with the release of high amount of energy.
For instance, fission of enriched Uranium.
Thus, there is high energy output in both the processes.
