Correct option is B
· Push-pull amplifiers are Class B amplifiers:
· Push-pull amplifiers are power amplifiers that use two transistors, one NPN and one PNP, to supply high power to a load. One transistor pushes current into the load during the positive half-cycle, while the other pulls current from the load during the negative half-cycle. This is why it's called a push-pull amplifier.
· Push-pull amplifiers are fundamental building blocks of electronics design and are used in many types of circuits, including high power, high fidelity, and digital high speed.
