The correct answer is C) Black gunpowder. Black gunpowder is classified as a low explosive or propellant, not a high-intensity explosive.

– High explosives detonate, producing a supersonic shockwave. Low explosives deflagrate (burn rapidly), producing a subsonic pressure wave.
– TNT (Trinitrotoluene), RDX (Research Department Explosive), and plastic explosives (which typically use RDX or PETN as the main component) are all examples of high explosives known for their destructive power and high detonation velocity.

Common examples of high explosives include TNT, RDX, PETN, C-4, Semtex, Dynamite, and Detonating Cord. Low explosives include black powder and smokeless powder. Black gunpowder is a mixture of potassium nitrate (or sodium nitrate), charcoal, and sulfur. It is primarily used as a propellant in firearms and pyrotechnics.
