Which action would be considered sabotage or vandalism?

The action of intentionally damaging property of a secured site is clearly identified as sabotage or vandalism. This behavior involves deliberate efforts to impair, destroy, or deface property, which goes against the principles of respect and care for shared resources and secured premises. Such actions not only cause financial loss but may also compromise the safety and security of the environment.

In contrast, reporting a broken light in a facility is a responsible action aimed at maintaining safety and operational efficiency. Posting flyers on notice boards is typically a form of communication that doesn't inherently cause harm, while normal wear and tear on equipment is an expected consequence of regular usage over time. Therefore, the only action among the options that constitutes sabotage or vandalism is the intentional damage to property, highlighting the distinction between responsible behavior and destructive actions.
