Which of the following best defines nonverbal harassment?

Nonverbal harassment is characterized by behaviors that communicate unwanted or inappropriate messages without the use of words. Suggestive gestures fall squarely into this category, as they can often imply sexual or threatening intentions without any verbal expression. Such gestures can create a hostile or uncomfortable environment for the recipient, contributing to a climate where harassment is prevalent.

In contrast, inappropriate touching involves physical contact, while insulting remarks consist of verbal abuse. Reporting to authorities is an action taken in response to harassment rather than a form of harassment itself. Therefore, suggestive gestures serve as the clearest representation of nonverbal harassment, making it the best definition among the given options.
