A signal of frequency $20 \mathrm{kHz}$ and peak voltage of 5 Volt is used to modulate a carrier wave of frequency $1.2 \mathrm{MHz}$ and peak voltage 25 Volts. Choose the correct statement.
Modulation index $=5$, side frequency bands are at $1400 \mathrm{kHz}$ and $1000 \mathrm{kHz}$
Modulation index $=5$, side frequency bands are at $21.2 \mathrm{kHz}$ and $18.8 \mathrm{kHz}$
Modulation index $=0.8$, side frequency bands are at $1180 \mathrm{kHz}$ and $1220 \mathrm{kHz}$
Modulation index $=0.2$, side frequency bands are at $1220 \mathrm{kHz}$ and $1180 \mathrm{kHz}$
