To date, the preferred weapons of mass destruction for terrorists have been

• A. Biological agents
• B. Chemical agents
• C. Nuclear devices
• D. Explosive weapons

Answer: (D)

Explosive weapons are favored because they are within reach for many groups and can cause mass casualties with relatively simple means. They can be assembled or deployed using materials that are widely available and do not require highly specialized facilities or extensive training. This practicality translates into a higher likelihood of a terrorist attack achieving widespread impact with minimal resources or risk to the attackers. In contrast, biological agents require complex production, controlled dissemination, and safeguards to handle dangerous pathogens; chemical agents demand precise delivery methods and protective measures; and nuclear devices depend on access to scarce fissile material, advanced engineering, and intricate safety controls. These barriers make such WMD capabilities far less attainable for nonstate actors and reduce their practicality for terrorist use. Because of these factors, explosives have historically become the most common WMD option in terrorist activity, guiding response planning toward blast-related injuries, fragmentation hazards, and the need for rapid mass-casualty management, scene safety, and multi-agency coordination.
