A poison that can be harmful if inhaled, swallowed, absorbed, or introduced into the body is:

• A. An Asphyxiant
• B. Toxic
• C. Corrosive
• D. A Virus

Answer: (B)

Toxic describes a substance that can harm the body through multiple routes of exposure—by inhalation, ingestion, absorption through the skin, or introduction into the body. This matches the idea of being harmful if inhaled, swallowed, absorbed, or introduced, since toxicity covers the potential for harm regardless of how exposure occurs. An asphyxiant mainly causes harm by displacing or reducing oxygen, not by general poisoning across all routes. A corrosive causes tissue damage on contact, typically burns rather than systemic poisoning via all exposure routes. A virus is a biological agent that can cause infection, which is a different kind of hazard than the broad chemical toxicity described here. So the best term for a poison that can harm through any exposure route is toxic.
