Which component starts the explosive chain to detonate a bomb?

• A. Primer
• B. Fuze
• C. Detonator
• D. Initiator

Answer: (B)

In any explosive system, the starting point is the initiating device that kicks off the entire explosive train. The fuze is that initiating device: when it’s activated, it provides the energy and timing needed to begin the sequence, which then triggers the next element in the chain (such as a primer or initiator) and ultimately detonates the main charge. Think of the fuze as the signal that starts the whole process. The other terms describe parts of the chain as they respond to or transmit that initiation: a primer is the sensitive explosive that must be detonated, the detonator delivers the shock to the main charge, and initiator is a general term for whatever starts the sequence in some systems. In this context, the fuze is the component that directly starts the explosive chain.
