Which of the following is an example of racial, national origin, or religious harassment?

Possession of items depicting racist organizations is a clear example of racial, national origin, or religious harassment because it directly includes symbols or representations that may promote hatred or discrimination against a specific race or ethnicity. Such items can create a hostile work or learning environment for individuals from targeted groups and can contribute to a culture of intimidation and fear.

In contrast, displaying motivational posters and conducting diversity training aim to foster positivity, inclusivity, and understanding among individuals of diverse backgrounds. These actions are intended to promote a supportive atmosphere rather than to undermine or offend any particular group. Similarly, organizing team-building events typically focuses on unity and collaboration, rather than exclusion or harassment. Therefore, those options do not align with the definitions of harassment based on race, national origin, or religion.
