Which of the following best describes sabotage?

The best description of sabotage is the act of intentionally damaging a facility for a specific purpose. This definition captures the essence of sabotage as it implies deliberate intent to cause harm or disruption to an entity, system, or operation. Sabotage can be motivated by various factors, including political, ideological, or financial motives, and is typically aimed at undermining the functionality or efficiency of an organization or its assets.

The other options reflect different actions or concepts that do not align with the definition of sabotage. Collaborating with others for improvement in security suggests a cooperative approach, which is the opposite of the destructive nature of sabotage. Defending against potential threats in the workplace focuses on protective measures rather than intentional harm. Assisting in lawful operations of a business implies support and compliance with legal standards, again distinctly separate from the disruptive and harmful intent associated with sabotage. Thus, option A is the most accurate representation of what sabotage entails.
