Solution
The correct option is D Fidelity
If a radio receiver amplifies all the signal frequencies equally well, it is said to have high fidelity.The fidelity at the lower modulating frequencies is determined by low-frequency response of the IF(Intermideat frequency) and the fidelity of the higher modulating frequencies is determined by the high-frequency response of the IF amplifier.Fidelity is difficult to obtain in AM receiver because good fidelity requires more bandwidth of IF amplifier resulting in poor selectivity.
