Answer» The CORRECT choice is (a) Varacter diode The best I can explain: Varactor diode is a diode working in the reverse-bias because of which no current flows through it. It has variable capacitance which varies with applied voltage. Varactor diodes are mainly USED in generation of FM signals USING Voltage Controlled Oscillator.
