Which term matches the definition: a verb used to indicate explosive effects capable of endangering life and property through blast, heat and projectiles?

• A. Detonation
• B. Explode
• C. Pyrophoric
• D. Deflagration

Answer: (B)

This question tests the verb used to describe an explosive event that can endanger life and property through blast, heat, and projectiles. Explode is the best fit because it directly denotes the act of an explosion and the harmful effects that follow. It’s a simple, widely understood verb for describing that kind of event. The other options don’t fit the requirement: detonation is a noun (and its verb form, to detonate, is more technical); pyrophoric describes a property of materials that ignite spontaneously; deflagration refers to a rapid but subsonic burning, not the general explosive blast described. So the straightforward verb that conveys those explosive effects is explode.
