Show answer & explanation
Correct answer: B
A walkie-talkie operates in Half-Duplex mode, allowing two-way communication where only one person speaks at a time. Simplex transmission is one-way only, while Full-Duplex permits simultaneous two-way communication. Multiplexing involves combining signals rather than defining transmission directionality.
