Best answer
Right answer is (c) Received power level

To explain I would say: Power amplifier is a part of RF front end section in transmit mode. It must be informed of transmit/receive mode to start and stop transmission. Transmitted power level, VSWR, and temperature are monitored for detection of abnormal behavour in power amplifier.
