$A$ sinusoidal carrier voltage of frequency $1.5 \, MHz$ and amplitude $50 \, V$ is amplitude modulated by a sinusoidal voltage of frequency $10 \, kHz$ producing $50 \%$ modulation. The lower and upper side-band frequencies in $kHz$ are:

  • A
    $1490, 1510$
  • B
    $1510, 1490$
  • C
    $\frac{1}{1490}, \frac{1}{1510}$
  • D
    $\frac{1}{1510}, \frac{1}{1490}$
