Best answer
Correct answer is (c) Good high frequency operation

The explanation: The high frequency response of multistage amplifiers circuit can be constructed with two configurations of a transistor that is CE (common – emitter) and CB (common base) . The CB (common base) configuration delivers a good high – frequency operation.
