उत्तर
A is true, but R is false.
Explanation:
Assertion (A) is true because smog is a severe form of air pollution that irritates the respiratory tract, causing conditions like asthma, chronic bronchitis, and lung infections. Reason (R) is false because smog is predominantly an urban and industrial phenomenon formed by the interaction of sunlight with vehicular emissions and industrial pollutants (smoke and fog), rather than from rural wood-burning for cooking.
