Correct answer: C
Summary: the true statements are identified and each statement is explained.
Full duplex communication is bidirectional. — True. Both parties can transmit and receive simultaneously (for example, a regular telephone call).
FM radio is an example of simplex communication. — True. Transmission is one-way from the station to listeners with no return channel.
Walkie-talkie is an example of full duplex communication. — False. Most walkie-talkies use push-to-talk and operate in half duplex: only one user transmits at a time.
In half duplex communication both devices can send and receive data at the same time. — False. Half duplex allows two-way communication but not simultaneous transmission; devices take turns to transmit.
A landline telephone is an example of half duplex communication. — False. Conventional landline telephones support simultaneous two-way voice (full duplex).
Correct statements: Full duplex communication is bidirectional; FM radio is an example of simplex communication.
