What activation-type categories are listed for landmines?

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

Answer: (A)

The activation types listed for landmines cover the main ways a mine can be triggered: blast, heat, and chemical. This means a mine could be armed to detonate from a mechanical impact or pressure that produces a blast, from exposure to heat that reaches a fuze’s threshold, or from a chemical sensor or chemical reaction that initiates detonation. Recognizing all three ensures you consider every plausible initiation method when assessing risk and planning safe handling or disarming. The other options omit one or more of these activation modalities, which would miss a possible triggering mechanism.
