Which of the following is NOT one of the seven Cs of effective communication?

The concept of the seven Cs of effective communication focuses on ensuring that messages are conveyed in a way that enhances understanding and engagement. Each "C" serves as a principle to guide communicators in delivering their messages effectively. The principles include clarity, conciseness, coherence, correctness, completeness, consideration, and courtesy.

In this context, clarity refers to making the message understandable, conciseness emphasizes delivering information in a brief yet comprehensive manner, and coherence relates to the logical flow of ideas throughout the message. The inclusion of "complicated" does not align with these principles; rather, it contradicts them. Effective communication aims to simplify complex information into digestible language, ensuring that the audience can readily grasp the key messages without confusion. Thus, "complicated" stands out as not fitting within the framework of the seven Cs.
