The emitter of which of the below mentioned transistors has electrons as the majority carriers?

Correct option is C

Electrons are the majority carriers in emitter
of NPN transistor.
Type of Transistors-

In an NPN transistor, the emitter is made of n-type material where electrons are the majority carriers. These electrons flow from the emitter to the base when the transistor is forward biased, facilitating the current flow through the device.
