Vapors can poison if they are inhaled or absorbed through the skin.

• A. Can poison if inhaled or absorbed through the skin
• B. Inhaled only
• C. Absorbed through the skin only
• D. Ingested only

Answer: (A)

Vapors can enter the body through more than one route, which is why both inhalation and skin contact matter. Breathing in vapors lets the substance travel to the lungs and into the bloodstream quickly, causing poisoning. Some chemicals can also be absorbed directly through the skin, so skin exposure can lead to poisoning even without inhalation. That makes the statement that vapors can poison if they are inhaled or absorbed through the skin accurate and complete. The other options are narrower: inhaled only ignores skin absorption, absorbed through the skin only ignores inhalation, and ingested only doesn’t apply to vapors unless they’re swallowed, which isn’t the focus here.
