@Pramod.
Total opposition offered by an AC circuit to flow of AC is called impedance.

DC Return means, sometimes the circuit gets reserve current called leakage current. In order to prevent return/excess currents, we have to use like Diodes or capacitors across affected elements.

The capacitor will be polar type to use in between source and load.

In a DC, the value of capacitive reactance is infinite because of frequency zero so in dc no return path is there.

capacitor blocks DC and allows AC,means it prevents the return of DC

Prevent means to avoid DC so capacitor block dc.
