What is defined as the expression of thoughts or feelings in words, symbols, or body language?

The correct answer is communication. Communication is a broad term that encompasses the process of expressing thoughts, feelings, and information through various means, including spoken or written words, symbols, and body language. It is an essential part of human interaction, allowing individuals to convey messages and exchange ideas effectively.

While "message" refers specifically to the content being conveyed—such as the spoken or written words—it does not encompass the entire process of conveying that information, which includes the sender, the medium, and the context of the interaction. Therefore, while "message" is related to communication, it is not as comprehensive of a term.

By recognizing communication as the overall process involving the expression of ideas in multiple forms, one can appreciate its role in facilitating understanding and collaboration between individuals.
