Which term is correctly paired with the description 'an article used for heat generation, gas generation and theatrical effect'?

• A. Ammunition
• B. Gun Powder
• C. Cartridge
• D. Pyrotechnic

Answer: (D)

The concept here is naming the type of article that generates heat, gas, and theatrical effects. Pyrotechnic items are specifically designed to create controlled heat, gas production, and visual or atmospheric effects used in theatre, film, and events. That combination—heat and gas generation coupled with a theatrical application—fits the category of pyrotechnic products, which are distinct from general weapon-related materials.

Ammunition, gun powder, and cartridge are all linked to weapons and propulsion rather than stage effects. They describe components or supplies used in firearms or explosive devices, not items intended for controlled theatrical displays.
