Which of the following is an example of an indirect approach to communication?

An indirect approach to communication typically involves methods that do not allow for immediate feedback or more personal engagement, often utilizing written forms of communication. Email, letters, or text messages exemplify this type of approach because they do not facilitate real-time interaction, allowing the sender to carefully compose their thoughts without the immediate pressure of responding to reactions from the recipient.

This format can introduce delays in feedback and may lack the nuances of verbal or face-to-face conversation, such as tone and body language, which can help convey meaning more effectively. Thus, using these written forms aligns with characteristics of indirect communication, making this answer the most fitting choice.
