They involve potential negative consequences, often linked to drug use.

• A. They always lead to positive outcomes.
• B. They are never illegal.
• C. They involve careful planning to avoid harm.
• D. Actions that involve potential negative consequences, often linked to drug use.

Answer: (D)

Risk in this context is about actions that could lead to harm or negative outcomes. The option that describes actions involving potential negative consequences, often linked to drug use, fits best because it directly defines risk as the possibility of harm and connects it to drug-related behaviours. It isn’t about always producing positive results, nor about legality being irrelevant, and it isn’t about planning to avoid harm—that would be more about harm-reducing strategies rather than describing risk itself.
