Answer & Explanation
The correct answer is Option A: May result from fires or automobile exhaust..
Carbon monoxide is a toxic, colorless, and odorless gas commonly produced by incomplete combustion in engines or fires. Because it binds to hemoglobin more effectively than oxygen, it poses a severe, life-threatening risk of hypoxia.
