D Correct answer
Explanation

Vehicle exhaust contains Carbon Monoxide (CO), a poisonous gas formed by incomplete combustion. The option spells it Monooxide which appears to be a typo for Monoxide. Asbestos is a building material, Carbon Tetrachloride is a solvent, and Chlorofluorocarbons (CFCs) were used in refrigeration but are not primary exhaust components.
