What might be a problem if you receive a report that your audio signal through an FM repeater is distorted or unintelligible?

Explicación

All three produce audio that arrives distorted or unreadable: an off-frequency transmitter is imperfectly demodulated by the repeater receiver, excessive microphone level or speaking too close over-deviates and clips, and a weak or multipath location gives the repeater a noisy signal to retransmit. Since each alone explains the report, the combined choice is correct.
