Right option is (d) Bandwidth

The explanation is: A Demodulation is a process of recovering the information signal from a modulated carrier wave, in which properties of a periodic waveform is varied. A modulator is a device that performs modulation while the demodulator performs demodulation. The process of mixing a signal with a sinusoid to produce a new signal is done by a mixer.
