Why is the audio taken from the detector through a coupling capacitor?
Answer: B
The detector output carries a direct voltage proportional to carrier strength, which must be kept out of the audio path while still being available to the gain control. A series capacitor does exactly that. De-emphasis is an FM network. Selectivity is set long before the detector. And loudspeaker matching is the output transformer's job. One component separating two uses of the same node is a small but characteristic piece of receiver design.
