here is ur ans.

Question :-

Why the message signal has low frequency ?

Answer :-

If the bandwidth is narrow enough and the center frequency is high enough and suitable for the channel to be used, then you don't even need a carrier (it could be 0 Hz for some modulation schemes). ...to send message signal over a long distance, when the frequency is low , energy will be obviously low.
