An information signal of frequency $10 \text{ kHz}$ is modulated with a carrier wave of frequency $3.61 \text{ MHz}$. The upper sideband and lower sideband frequencies are:
- A$3650 \text{ kHz}$ and $3590 \text{ kHz}$
- B$3620 \text{ kHz}$ and $3600 \text{ kHz}$
- C$3610 \text{ kHz}$ and $3580 \text{ kHz}$
- D$3600 \text{ kHz}$ and $3620 \text{ kHz}$
