Two components of pipe bombs

• A. High explosives and fuse
• B. Low explosives and fuse
• C. Casing and primer
• D. Detonator and battery

Answer: (B)

When thinking about a pipe bomb, the essential pieces are the explosive charge and the way it’s ignited. The typical, simple setup uses a low explosive as the charge and a fuse as the ignition method. The low explosive is chosen because it burns rapidly inside a confined container to build up pressure, causing the pipe to fail and release energy. The fuse provides a straightforward, timed way to start that burning without requiring complex electronics or detonation systems.

Higher-order explosive types would behave differently and aren’t aligned with the classic, straightforward pipe-bomb concept. A mere casing with a primer or a detonator-and-battery introduces additional devices and initiation methods that aren’t part of the simplest, most common description used in safety and forensic contexts. The combination of a low explosive with a fuse captures the basic idea of a simple, ignition-triggered charge inside a pipe.
