Vedclass · Answer

(D) In an $NPN$ transistor,the majority charge carriers are electrons,whereas in a $PNP$ transistor,the majority charge carriers are holes.Electrons have higher mobility than holes because they are lighter and interact differently with the crystal lattice.Due to this higher mobility,$NPN$ transistors offer faster switching speeds and better performance compared to $PNP$ transistors.Therefore,$NPN$ transistors are preferred over $PNP$ transistors.

$NPN$ transistors are preferred to $PNP$ transistors because they have
