Answer

Answer:

B. critical mass

Brief Explanation:

A critical mass is needed to start a fission reaction. It's the minimum amount of fissile material for a self - sustaining chain reaction. A chain reaction is the process that occurs after reaching critical mass. Neutron absorption and moderation are processes during the reaction, not the key to starting it.
