C) FDMA
D) CDMA

FDMA (Frequency Division Multiple Access) is a technique that divides the bandwidth of the frequency into several narrower frequencies. Each user then transmits using its own narrower frequency channel. This allows multiple users to share the same frequency band. TDMA (Time Division Multiple Access), on the other hand, divides the signal into time slots and each user takes turns transmitting during their assigned slots. OFDM (Orthogonal Frequency Division Multiplexing) is a technique that divides the signal into multiple small sub-carriers that are then transmitted simultaneously. CDMA (Code Division Multiple Access) is a technique where each user is assigned a unique code to transmit and multiple signals are transmitted in the same frequency band at the same time, but each signal can be distinguished from the others using the unique code.
