B. Nuclear fission reactions are slowed down as well.
Neutron moderation is a substance which slows down neutron. In some reaction moderator is same as coolant.
This is also used to slow down nuclear fission reaction and continue chain reactions.
The collision between neutron and nuclei is more elastic and more neutrons will be slowed due to size of the neutron.
