In amplitude modulation

A
Amplitude remains constant but frequency change
B
Both amplitude and frequency do not change
C
Both amplitude and frequency change
Correct answer
D
Amplitude of the carrier wave changes according to information signal

Solution

In amplitude modulation amplitude of the carrier wave changes according to information signal.

Hence, the correct answer is option: 'D'.
