According to communication statistics, the percentage of a message received is largely influenced by what factor?

The correct answer highlights the significance of not only the content of a message but also the manner in which it is delivered. "How" pertains to the delivery style, including tone, body language, and emotional resonance, which can greatly influence the interpretation and reception of the message. For instance, a message conveyed with enthusiasm and clarity may be far more effective than one that is monotonous or unclear.

Additionally, "what" refers to the actual content or information being communicated. The clarity, relevance, and structure of the message are crucial for ensuring that the audience comprehends the intended meaning. Together, "how" and "what" capture the critical components of effective communication, indicating that both the substance and the method of delivery are essential for ensuring that a message is received as intended.

In contrast, the other choices mix different elements that do not encapsulate the dual influence of content and delivery style as effectively. For instance, options involving "when," while potentially important in certain contexts, do not address the core dynamics of message reception in the same comprehensive manner as "how" and "what." Thus, the emphasis on both delivery and content in the correct choice reinforces the multifaceted nature of effective communication.
