Solution

The correct option is C Antenna.
Antenna is the only device that helps in transmitting the message signals in any communication system .So,in AM modulation the modulated signal is transmitted and amplified with help of anteena.

Q. Assertion :The modulation index (or modulation depth) of a modulation scheme describes by how much the modulated variable of the carrier signal varies around its normal modulated level Reason: In plate modulation, the plate voltage of the RF amplifier is modulated with the audio signal. The audio power requirement is 50 percent of the RF-carrier power.
