Ask EduPadi AI for a detailed answer
Correct Option: B
Carbon monoxide is produced as a byproduct of incomplete combustion of carbon-containing fuels. In urban settings, vehicles, especially those powered by internal combustion engines, release carbon monoxide into the air as part of their exhaust gases. Poorly tuned engines, inefficient combustion, or inadequate ventilation contribute to higher concentrations of CO in areas with heavy traffic.
Therefore, the correct answer is Vehicle emissions.
