A `0K` temperature, a `p`-type semiconductor

Answer

A

Explanation

Conductor are those through which electric charge can easily flow, while insulators are those through which electric charge is difficult to flow. Solids whose electrical conductivity is intermediate between conductors and insulators are called semiconductors. At absolute zero a `p`-type semiconductor which has holes as charge carriers behaves like an ideal insulator and hence it has a few holes in valence band but no free electrons.
