Components of a bomb are listed as which of the following?

• A. Timing device/switch, power supplies/battery, explosives, and initiator/detonator
• B. Fuse, wiring
• C. Battery, circuit board
• D. Gas canister, valve, tubing, filter

Answer: (A)

Think of a complex energy-release device in terms of four essential subsystems: something to decide when to release the energy (a timing device or switch), a power source to run the electronics (batteries or similar supplies), the energetic payload itself (the explosive material), and a mechanism that actually initiates the release (an initiator or detonator). The option that lists all four of these elements captures how such a device is organized at a conceptual level. The other choices miss at least one critical part or include components that don’t fit how such devices are structured, like items unrelated to controlled energy release. This helps you see why that answer best matches the general way we classify the parts needed for a hazardous device, while keeping the discussion at a safe, non-procedural, educational level.
