Yes. You are right @Avinash.

I think distant side bands decrease. Because at the constant modulating voltage and lower modulating frequency, the modulation index is very large. And it comes in the category of wideband frequency modulation. In which frequency domain representation of wide band gives us that side bands are decreased.
