The correct answer is C) Acetone peroxide.
1. Gunpowder and smokeless powder are examples of low explosives, not high explosives. Low explosives burn rapidly but do not detonate.
2. Acetone peroxide is an example of a high explosive. High explosives detonate, producing a supersonic shockwave.
3. Fireworks are not typically classified as high explosives. They involve combustion and do not create a shockwave characteristic of high explosives.
