Which fuse is made from a fuse of string impregnated with black powder?

• A. Safety Fuse (Visco Fuse)
• B. No Fire Current
• C. Fusee
• D. Black Match

Answer: (D)

The thing being tested is recognizing fuse construction by name. A fuse made from string that has been soaked in black powder is known as Black Match. This is a simple, primitive fuse where the string itself carries the ignition material, so it lights along its length when exposed to flame. It contrasts with other fuses: safety fuses (Visco) use a slow-burning, polymer-bonded core for a controlled delay, and a fusee is a different slow-burning fuse with its own construction and use. Black Match is the specific description that matches a fuse made from string impregnated with black powder, which is why it’s the correct choice.
