Solution

The correct option is A Both A and R are correct and R is the correct explanation of A
Pesticides are basically synthetic toxic chemicals with ecological consequences. The repeated use of the same or similar pesticides gives rise to pests that are resistant to that group of pesticides thus making the pesticides ineffective.

These pesticides are organic toxins, water-insoluble and non-biodegradable and thus causes soil and water pollution.

Thus, both Assertion and Reason are correct and Reason is the correct explanation of Assertion.

Hence, option (A) is the correct answer.
