Which of the following is a common characteristic of victim-operated IEDs?

Victim-operated IEDs are designed to detonate when an unsuspecting individual interacts with them, which often occurs when they are concealed in locations where people frequently pass. This characteristic makes option B the correct choice. By placing these devices in common pathways, the perpetrators increase the likelihood of an unsuspecting victim triggering the explosion.

The other options do not accurately represent the typical characteristics of victim-operated IEDs. Many such devices avoid remote detonation mechanisms, focusing instead on triggering through direct attention or accidental interaction. Additionally, while certain IEDs may involve complex detonation phases, victim-operated devices are generally designed for immediate activation upon contact. Finally, the explosives used can vary widely, and while some may be difficult to acquire, it’s not a defining trait of victim-operated IEDs specifically.
