What are the six classes of Weapons of Mass Destruction (WMD)?

The correct answer highlights types of chemical agents that fall under the weapons of mass destruction classification. The six classifications referenced include nerve agents, vesicants (blister agents), blood agents, choking agents, irritants, and biological toxins. These categories cover a range of harmful effects that can be unleashed on large populations, affecting public health and safety.

Nerve agents disrupt the normal functioning of the nervous system, vesicants cause blistering and damage to skin and mucous membranes, blood agents interfere with the body’s ability to use oxygen, choking agents can lead to respiratory distress, irritants cause inflammation and discomfort, and biological toxins include a variety of harmful microorganisms or their byproducts. Knowing these classifications is crucial for first responders and hazardous materials teams to effectively identify and respond to incidents involving WMDs.

The other choices refer to various hazardous materials but do not accurately capture the specific six classes recognized under the WMD classifications. While they each discuss dangerous materials in their own right, they do not encompass the full range of categorization necessary for understanding and managing weapons of mass destruction in emergency response scenarios.
