Correct answer: C
To identify the true statements, we evaluate each communication mode:
Statement A is true: Full duplex allows simultaneous two-way communication.
Statement B is true: FM radio transmits from a station to listeners only, which is simplex.
Statement C is false: Walkie-talkies are half-duplex, allowing only one-way transmission at a time.
Statement D is false: Half-duplex does not permit simultaneous sending and receiving.
Statement E is false: Landline telephones use full-duplex for simultaneous conversation.
Thus, statements A and B are the correct options.
