How many initiation methods are listed for IEDs?

• A. 2
• B. 3
• C. 4
• D. 5

Answer: (B)

Initiation methods refer to how an IED is triggered. In this material, initiation methods are described as remote initiation, timing initiation, and victim-activated initiation. This listing represents the complete set presented in the context, helping you understand the different ways devices can be activated. Knowing these categories informs protective actions: remote initiation means maintaining distance and shielding, timing initiation involves a countdown that requires swift evacuation, and victim-activated initiation highlights triggers that can be activated by a person, prompting immediate movement away from the area. The other options would either add non-listed categories or omit one of these described modalities.
