Diking, damming, and diverting are ______ options available for ______ control.

• A. Offensive; containment
• B. Defensive; spill
• C. Proactive; leak
• D. Passive; exposure

Answer: (B)

Diking, damming, and diverting are defensive, physical containment measures used to prevent a hazardous liquid from spreading after a release. They create barriers or redirects that keep the material from moving into new areas, helping protect people, property, and the environment. That’s why they fit as defensive options for spill control—they’re actions taken to defend against a spill and limit its impact. The other descriptors don’t apply as well: these aren’t about attacking or advancing the hazard (offensive), nor are they simply passive or non-action-oriented; they are active containment actions aimed specifically at stopping or steering the spill.
