The seven Cs of communication include clear, concise, concrete, correct, coherent, complete, and:

The seventh C of communication is courtesy. Courteous communication emphasizes the importance of respect and politeness in interaction, which can greatly enhance the effectiveness of the communication process. Being courteous helps to build trust and rapport between the communicator and the audience, making it more likely that the message will be well received.

When communication is respectful and considerate, it acknowledges the feelings and perspectives of others, which can lead to more fruitful discussions and a collaborative atmosphere. This is especially important in professional settings, such as nursing, where effective communication can significantly impact patient outcomes, teamwork, and overall workplace morale.

The other options, while they may enhance communication in certain contexts, do not specifically pertain to the established principles that define effective communication in the seven Cs framework. For example, compelling may relate to making the message engaging, but it is not one of the classic Cs. Similarly, careful communication might imply attention to detail, and collaborative suggests working together, but neither fits within the original framework of the seven Cs.
