00:00The question says, for a PNP transistor, the n-type crystal X is A collector only, B emitter
00:19only, C base only, D either emitter or collector. In PNP transistor, the emitter is P-type, base
00:39is n-type and collector is P-type. So, in PNP transistor, emitter and collector are P-types,
00:51but base is n-type. So, the correct option will be C base only.
