What is DC return?

Then how the capacitor allows dc to flow from source to load?

What is meant by dc return?

Have some doubts. The options should include diode, optocoupler etc. Because as caps blocks dc, there will be no current from source to load either. The purpose of using caps in dc circuit is to provide stability i.e. parallel connection across loads.

Capacitor allows only AC but blocks DC.

Dc return replace by dc current and answer C is right because capacitor creates high reactance on low frequency current. Xc = 1/2piefc.
