Ferrite material is

A The most fissionable material
B The basic fuel for nuclear paints
C Basic raw material for nuclear plants
D The material which absorbs neutrons and undergoes spontaneous changes leading to the formation of fissionable material

Correct Answer: The material which absorbs neutrons and undergoes spontaneous changes leading to the formation of fissionable material

Fertile material is a material that although not itself fissionable by thermal neutrons, can be converted into a fissile material by neutron absorption and subsequent nuclei conversions.
