Explanation

The correct answer is (B) Ammonia.

Ammonia is not typically a pollutant found in vehicular exhaust emissions. Vehicular exhaust emissions primarily contain pollutants such as carbon monoxide (option C), particulate matter (option D), nitrogen oxides, hydrocarbons, and in the past, lead (option A) from leaded gasoline. While ammonia can be emitted from other sources such as agricultural activities and industrial processes, it is not a primary component of vehicular exhaust emissions.
