FM is advantageous over AM as
A. The amplitude of FM is constant. So transmitter power remains unchanged in FM but it changes in AM
B. The depth of modulation in FM can be changed to any value by changing the frequency deviation. So the signal is not distorted
C. There is less possibility of adjacent channel interference due to presence of guard bands
D. All of the above
