Which activation-type combination best reflects the fuzing types listed for blast, heat, and chemical landmines?

• A. Blast, Heat, Chemical
• B. Blast, Heat
• C. Pressure
• D. Pull

Answer: (A)

Activation types can be combined in a single mine, so the best match is the profile that includes all listed triggers. If a mine is described as being activated by blast, heat, and chemical, the activation-type combination must reflect each of those stimuli. A blast fuze responds to a shock or pressure event, a heat fuze responds to elevated temperature, and a chemical fuze responds to a chemical trigger. Therefore, listing blast, heat, and chemical together accurately covers every activation modality described. Choosing a combination that omits one of these—such as only blast and heat, or focusing on a single type like pressure or pull—does not capture all the fuzing modalities specified.
