A) \[{{n}_{e}}>{{n}_{h}}\]if the semiconductor is intrinsic

B) \[{{n}_{e}}<{{n}_{h}}\]if the semiconductor is intrinsic

C) \[{{n}_{e}}\ne {{n}_{h}}\]if the semiconductor is intrinsic

D) \[{{n}_{e}}={{n}_{h}}\]if the semiconductor is intrinsic

E) \[{{n}_{e}}={{n}_{h}}\]if the semiconductor is extrinsic
