Which amplifier is preferably used for low level modulation?(a) Class

1.	Which amplifier is preferably used for low level modulation?(a) Class C(b) Class A(c) Class AB(d) Class BThis question was addressed to me in an interview.Asked question is from AGC in portion Receivers & Transducers of Analog Communications
Answer» The correct option is (B) Class A To elaborate: We called a MODULATION as LOW level when the modulation takes place prior to the output element of the final stage of the amplifier at low power. Class A AMPLIFIERS are used for this PURPOSE.
