Diking, damming, and diverting are which type of control options for spills?

Answer: D — Defensive; Spill

Defensive measures are used to keep the spilled material from spreading and causing more harm, rather than stopping the source of the release. Diking, damming, and diverting create barriers and redirects that contain the liquid in a controlled area, protecting people, property, and the environment. This is containment in action, focusing on limiting environmental impact rather than eliminating the source of the release. The other terms describe actions aimed at stopping the release itself or use terminology that isn’t the standard way to categorize spill-control options, so they don’t fit as well for this scenario.
