The most suitable class of amplifier for a high fidelity radio transmitter is
- B.
- C.
- A.
Explanation from PART66Online
Class A is the most suitable for high-fidelity work because the transistor conducts over the full 360 degrees of the input cycle, so the output is a faithful, low-distortion reproduction of the input. Classes B and C only conduct for part of the cycle and introduce crossover or severe waveform distortion, making them unsuitable where fidelity matters most.

Class C is specially designed for RF and only that and can't be used for audio

A. High fidelity means low distortion, Class A is most linear, Class C is efficient for RF but distorts too much for clean audio.
