Correct Answer - Option 1 : Selectivity
Selectivity:
The selectivity of the receiver is defined as its ability to accept or select the desired band of frequency & reject all other unwanted frequencies which can be interfering signals.
Fidelity:
The fidelity of a receiver is its ability to reproduce the exact replica of the transmitted signals at the receiver's output.
Sensitivity:
The sensitivity of a receiver is its ability to identify & amplify weak signals at the receiver’s output.
Distortion:
Alteration of a waveform at any frequency component.
From above we conclude that option (1) is correct.
