Which statement is true regarding Frequency

Q: Answer-Which statement is true regarding Frequency Modulation(FM)?

In Frequency Modulation FM, the carriers frequency changes according to the instantaneous amplitude of the message signal, while the amplitude of the carrier remains constant . This makes FM less susceptible to noise compared to Amplitude Modulation AM, since most noise affects amplitude. Although frequency is the main varying parameter, phase is indirectly related to frequency change, but the amplitude stays fixed. This is why FM provides better sound quality and higher noise immunity, making it widely used in radio broadcasting.

Modulation(FM)?

A In FM amplitude is constant but Phase varies.

B In FM both amplitude and phase vary but frequency remains constant.

C In FM amplitude varies and Phase remains constant.

D In FM frequency varies and amplitude and phase remain constant.
