Carbon Monoxide is:

Explanation:
Carbon monoxide is a colorless, odorless, toxic gas formed when carbon-containing fuels burn with insufficient oxygen. Incomplete combustion means not all carbon becomes carbon dioxide; some remains as CO. Because it has no smell or color, it can accumulate unnoticed, and it is dangerous because it binds strongly to hemoglobin, reducing the blood’s ability to carry oxygen. It’s not produced by complete combustion (that makes carbon dioxide), not a color gas formed in chlorinated water, and not a solid pollutant from soil erosion. So the description that fits best is a colorless, odorless toxic gas formed by incomplete combustion.
