Correct option is B
Simplex communication is a one-way communication mode where data flows only in one direction from sender to receiver with no return channel for feedback or response.
Radio broadcasting (A) and Television broadcasting (B) are classic examples of simplex communication since signals are transmitted from the station to the audience without any feedback from the receiver.
Computer to Printer communication (C) is simplex because data flows only from the computer to the printer; the printer does not send data back to the computer in typical printing operations.
Keyboard to computer communication (D) is also simplex, where the keyboard sends input signals to the computer but does not receive any data back.
Walkie-Talkie communication (E) is not simplex; it is half-duplex, meaning communication can occur in both directions but only one direction at a time (push-to-talk).
Information Booster:
Simplex communication is unidirectional and typically used in broadcasting and some peripheral device communications.
Half-duplex allows communication both ways but not simultaneously (e.g., walkie-talkies).
Full-duplex communication allows simultaneous two-way data flow (e.g., telephone calls).
Simplex systems are simpler and often cheaper due to one-way data flow.
Examples of simplex include television, radio, keyboards, and printers.
