Answer: D
The commonly used mode for 3G networks is FDD, frequency division duplex.
Most 3G systems, including UMTS with W-CDMA and CDMA2000, use paired frequency bands, one for the uplink and one for the downlink, which is frequency division duplex. TDD versions such as TD-SCDMA were deployed far less widely.
TDMA is the access method of 2G GSM and is not the 3G mode, and CSMA is the contention method of local area networks such as Ethernet and Wi-Fi.
