In Am frequency and phase must be kept constant and the amplitude is varied with respect to frequency.
A = Amsin (wot+phase).
A = Amsin (wot+phase).

In amplitude modulation the amplitude of the carrier is varied according to the modulating(baseband) signal.

Amplitude modulation (AM) itself indicating the change in amplitude. So answer will be amplitude.

Hai amplitude modulation is defined as ''amplitude of a carrier is varies in accordance with the modulating wave'' so option A is correct.

As it is in Amplitude Modulation,From Definition as "amplitude is varied with respect to modulating signal"

In case of AM(amplitude modulation) which is by it's name specially done to modulate amplitude of carrier signal.
