Answer

Brief Explanations:

A critical mass is the minimum amount of fissile material needed to start a self - sustaining nuclear fission chain reaction. A chain reaction is the process that occurs after the critical mass is reached. Neutron absorption and moderation are processes that occur during a fission reaction but are not the key factor to start it.

Answer:

B. critical mass
