Let \( \mathrm{n}_{\mathrm{h}} \) and \( \mathrm{n}_{\mathrm{e}} \) be the number of holes and conduction electrons in an extrinsic semiconductor. Then
(a) \( \mathrm{n}_{\mathrm{h}}\mathrm{n}_{\mathrm{e}} \)
(b) \( \mathrm{n}_{\mathrm{h}}=\mathrm{n}_{\mathrm{e}} \)
(c) \( \mathrm{n}_{\mathrm{h}}\mathrm{n}_{\mathrm{e}} \)
(d) \( \mathrm{n}_{\mathrm{h}} \neq \mathrm{n}_{\mathrm{e}} \)
\( \mathrm{P} \)
