Solution

The correct option is C Intrinsic
In the case of semiconductors, electron-hole pairs are generated only due to the breaking of covalent bonds. There is no other source of generation of electron-hole pairs. Hence when the electrical conductivity of a semiconductor is only due to the breaking of its covalent bonds, then the semiconductor is said to be an intrinsic semiconductor.
