Which of the following is not one of the 3 C's in communication?

The concept of the 3 C's in communication emphasizes the importance of being clear, consistent, and confident when conveying information. Clarity ensures that the message is easily understood, allowing the audience to grasp the key points without confusion. Consistency helps maintain trust and credibility, as it reinforces the message over time and across different platforms. Confidence in delivery conveys authority and belief in the message being shared, making the communication more effective.

The option concerning "casual" is not recognized as one of the fundamental principles in effective communication. While being casual may have its place in certain contexts, it does not align with the core qualities defined by the 3 C's, which focus on enhancing understanding and impact rather than on a relaxed or informal style.
