Which term refers to improvised explosives made using common equipment and ingredients found in clandestine labs?

• A. Commonly encountered homemade explosives that are highly sensitive to heat, shock, or friction.
• B. TATP and HMTD
• C. Explosives that detonate with a chemical reaction moving faster than the speed of sound.
• D. Improvised explosives made using common equipment and ingredients found in clandestine labs.

Answer: (D)

The main idea here is understanding what an improvised explosive is: a device assembled from readily available materials and common equipment found in places like clandestine labs, rather than a purpose-built, commercially produced explosive. The term described matches that concept exactly, highlighting the makeshift nature and the use of everyday items to create an explosive.

This distinguishes it from references to specific substances (which would name particular explosives), from a general property like detonation speed, or from broad categories of homemade explosives. So the description that defines improvised explosives made with common equipment and ingredients found in clandestine labs is the best fit.
