B) slope diode.
C) photo diode.
D) zener diode.

Question

Quizplus · Accepted Answer

A slope diode, also known as a varactor diode, is able to change its capacitance with applied voltage. This property makes it useful in frequency multiplier circuits where it is used as a voltage-controlled capacitor to vary the resonant frequency of the circuit. Photo diodes are used to detect light, while zener diodes are used in voltage regulation circuits.
