Answer: D

Explanation:

The linear modulation techniques include BPSK (Binary Phase Shift Keying), QPSK (Quadrature Phase Shift Keying), π/4 QPSK and OQPSK (Offset Quadrature Phase Shift Keying). These modulation schemes are preferred in wireless communication systems because they have good spectral efficiency, low error rates, and the ability to transmit high data rates. FSK (Frequency Shift Keying) is a non-linear modulation technique that is not as efficient as linear modulation techniques. In FSK, the frequency of the carrier signal is varied to transmit digital information.
