Which communication is one-way?

Communication can be categorized as one-way or two-way, depending on the flow of information and feedback. One-way communication involves a sender transmitting information to a receiver without immediate or direct feedback. A lecture is the correct answer as it exemplifies one-way communication. During a lecture, the instructor primarily delivers information to a largely passive audience, with minimal immediate interaction or opportunity for the audience to provide direct feedback or ask questions during the main delivery.

• Discussion inherently involves two-way communication, with participants exchanging ideas, asking questions, and providing feedback to each other.
• Debate is a highly interactive form of two-way communication where opposing sides present arguments and rebuttals, directly responding to each other.
• Group work relies heavily on multi-way communication among group members to achieve shared goals, involving constant interaction and feedback, making it distinctly two-way.
