Correct answer: C
Concept
A transmission mode classifies communication by the direction in which information can flow. Simplex is one-way; half-duplex is two-way but alternate; full-duplex is two-way and simultaneous.
Application
In a television or radio broadcast, the broadcasting station sends signals to receivers. The receivers do not send information back to that station over the same broadcast link.
Cross-check and contrast
Automatic describes operation without manual intervention rather than a direction of information flow.
Half-duplex requires both ends to transmit, taking turns.
Full-duplex requires both ends to transmit at the same time.
Therefore, television and radio broadcasting use simplex transmission.
