At $0 \mathrm{~K}$ temperature, a $p$-type semiconductor
At $0 \mathrm{~K}$ temperature, a $p$-type semiconductor
does not have any charge carriers
has few holes but no free electrons
has few holes and few free electrons
has equal number of holes and free electrons.
Solution
At $0 \mathrm{~K}$ temperature, a pure semiconductor behaves as an insulator, because it has a few holes in its valence band. But there is no free electron in this state.
