A fission chain reaction in uranium can be developed

A. By increasing the contents of U₂₃₅

B. By slowing down fast neutrons so that U₂₃₅ fission continues by slow neutron

C. Both (A) and (B)

D. None of these

Answer: Option C

Solution(By Examveda Team)

Nuclear chain reactions are series of nuclear fissions (splitting of atomic nuclei), each initiated by a neutron produced in a preceding fission.
A fission chain reaction in uranium can be developed by increasing the contents of U₂₃₅ and by slowing down fast neutrons so that U₂₃₅ fission continues by slow neutron.
