Which agent is capable of causing general destruction of tissue and inflammation?

The correct choice is the blister agent. Blister agents, such as mustard gas, are chemical warfare agents that cause severe damage to skin, eyes, and respiratory tract. They induce blistering and can lead to significant tissue destruction and inflammation due to their corrosive properties.

When blister agents come into contact with the body, they disrupt cellular membranes, leading to cellular injury and inflammation. The response from the body includes a variety of symptoms, such as blister formation on the skin, respiratory issues if inhaled, and potential long-term damage to the affected tissues. This capability to cause widespread tissue damage and inflammation makes blister agents particularly dangerous in warfare scenarios.

While other agents mentioned have their own harmful effects, they target the body in different ways. Nerve agents disrupt the nervous system, blood agents interfere with oxygen transport, and choking agents primarily attack the respiratory system, but none possess the same destructive tissue properties as blister agents.
