What best defines miscommunication?

Miscommunication is best defined as an unclear transmission of information. This definition highlights the core issue that arises when the intended message is not conveyed accurately or is misunderstood by the recipient. Miscommunication can occur due to various factors such as ambiguous language, cultural differences, lack of feedback, or distractions during the conversation.

In contrast, the other options illustrate aspects of effective communication rather than miscommunication. Clear exchange of ideas and effective dialogue both imply that the information shared is understood as intended, which is the opposite of miscommunication. Understanding expressed emotions also involves clear communication, focusing on emotional context rather than the clarity of the transmitted message. Thus, option B accurately encapsulates the essence of what miscommunication entails.
