Vedclass · Answer

(D) In $NPN$ transistors,electrons are the majority charge carriers,whereas in $PNP$ transistors,holes are the majority charge carriers.Electrons possess significantly higher mobility compared to holes due to their smaller effective mass and different scattering mechanisms in the crystal lattice.Because of this higher mobility,$NPN$ transistors exhibit faster switching speeds and better performance characteristics.Therefore,$NPN$ transistors are preferred over $PNP$ transistors.

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