The reaction depicted in the figure would take place in which of the following?

fisson reactor

i dont know if this is right i belive it is

Option (a) is the correct answer.

Explanation:

Nuclear fission is defined as a reaction in which a heavy nucleus splits into two or more small nuclei along with emission of energy.

For example,

So, the given diagram shows a large nucleus is splitting into two small nuclei. Therefore, it is a nuclear fission reaction.

Whereas a nuclear reaction in which two small nuclei combine together to result into the formation of a large nucleus is known as a nuclear fusion reaction.

Thus, we can conclude that the reaction depicted in the figure would take place in fission reactor.
