Right choice is (d) More than one

Easy explanation: A multistage amplifier circuit affects the high input impedance of a common source stage combined with the input to output isolation of a common gate stage. A radio receiver has more than one stage of amplification because it is required to restore the characteristics of a radio signal over various channels.
