C Correct answer
Explanation

Traditional black powder (gunpowder) is a mixture of potassium nitrate (nitre/KNO3), sulfur, and charcoal in approximately 75:15:10 ratio. The charcoal provides fuel, sulfur aids combustion and lowers ignition temperature, and nitre supplies oxygen for rapid burning. TNT is a modern explosive, not part of traditional gunpowder; sand is an inert filler.
