Which of the following is an example of non-contact sexual misconduct?

The correct choice represents a clear example of non-contact sexual misconduct because it involves inappropriate and explicit communication without any physical interaction or contact. Sending nude photos constitutes a violation of personal boundaries and creates a situation that can be seen as harassment or exploitation, especially in a position of authority, such as that of a coach. This behavior not only demonstrates a lack of professionalism but also undermines the trust and safety essential in an athletic environment.

In contrast, the other choices involve either positive actions or disciplinary measures that do not constitute sexual misconduct. Encouraging healthy relationships and providing support resources focus on fostering a safe and respectful environment, while suspending an athlete is a disciplinary action that, while serious, does not imply any form of sexual misconduct. Thus, the nature of the action in the correct answer is what categorizes it distinctly as non-contact sexual misconduct.
