The correct answer is: 4) FDD (Frequency Division Duplexing)

Explanation: In 3G networks, the most commonly used mode for communication is FDD (Frequency Division Duplexing).

FDD (Frequency Division Duplexing):

Uses separate frequency bands for uplink and downlink communication.
Provides continuous transmission, reducing latency.
Widely used in UMTS (WCDMA-based 3G networks).

Why not the others?

TDMA (Time Division Multiple Access) → Used in 2G (GSM) but not common in 3G.
FDMA (Frequency Division Multiple Access) → Used in older analog systems (1G).
TDD (Time Division Duplexing) → Used in some 3G implementations but not as widely as FDD.

Final Answer: (4) FDD
