Q. Let $n_{e}$ and $n_{h}$ represent the number density of electrons and holes in a semiconductor. Then
A) $n_{e}$ > $n_{h}$ if the semiconductor is intrinsic
B) $n_{e}$ < $n_{h}$ if the semiconductor is intrinsic
C) $n_{e}$ $\neq$ $n_{h}$ if the semiconductor is intrinsic
D) $n_{e}$ = $n_{h}$ if the semiconductor is intrinsic
Explanation
(d) In an intrinsic semiconductor, $n_{e}$ = $n_{h}$
