Correct answer is (a) High gain and high bandwidth

Easy explanation: A circuit having a single transistor amplifier does not provide suitable bandwidth or gain. To overcome this difficulty, we combine several amplification stages. The cascading transistor amplifier theory is used for high gain as well as high bandwidth.
