Which option is NOT one of the four Cs used when dealing with suspicious items?

• A. Confirm
• B. Clear
• C. Communicate
• D. Contain

Answer: (D)

When you’re dealing with a suspicious item, you follow four clear actions that all start with the letter C: Confirm, Contain, Clear, Communicate. Each step helps you manage risk in a practical order. Confirm means checking and validating what you’re dealing with, to avoid acting on assumption. Contain is about restricting the item’s movement and preventing harm or spread. Clear involves moving people away from the area to keep everyone safe. Communicate ensures the right people are informed—control room, supervisors, and those who need to know—so everyone coordinates the response.

In this question, every option listed is one of those four Cs, so none of them is a choice that isn’t part of the set. If a test marks Contain as not part of the four Cs, that would be inconsistent with the standard protocol. The key idea to take away is that Contain is indeed one of the four Cs, alongside Confirm, Clear, and Communicate.
