What type of communication allows immediate interaction among participants?

The type of communication that allows immediate interaction among participants is synchronous communication. This method is characterized by real-time exchanges, meaning all participants can respond and engage simultaneously, fostering a dynamic dialogue. Examples of synchronous communication include meetings, video conferences, and phone calls, where all parties are present at the same time to discuss and share information interactively.

In contrast, asynchronous communication occurs when participants engage at different times. This includes methods like emails or recorded messages, where responses can be delayed, leading to a lack of immediate interaction. Formal communication pertains to structured information channels within organizations, while written communication references the format in which information is conveyed, but does not inherently imply immediacy or real-time interaction. Therefore, synchronous communication stands out as the correct choice for facilitating immediate discussion between participants.
