The Class-B push-pull amplifier is an efficient two-transistor circuit, in which the two transistors operate in the following way:

A. Both transistors operate in the active region throughout the negative ac cycle

B. Both transistors operate in the active region for more than half-cycle but less than a whole cycle

C. One transistor conducts during the positive half-cycle and the other during the negative half-cycle

D. Full supply voltage appears across each of the transistors

Answer: Option C
