Solution
The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion. Kanpur is the most polluted city in the country, with high quantities of respirable suspended particulate matter (RSPM) in the air, according to the results of a survey carried out by the 'Central Pollution Control Board' (CPCB) in 2002.
