A Correct answer
Explanation

100BaseT4 uses four pairs of Category 3 (or better) cabling. Because it requires three pairs to transmit or receive data simultaneously in one direction, it cannot support full-duplex operation. 10BaseT and 100BaseTX only require two pairs and can operate in full-duplex mode.
