• A. Produce immunity against mosquito.
• B. Cause leukemia (blood cancer) in most people.
• C. Cause cancer of the intestine.
• D. Lead to accumulation of pesticide residues in body fat.

Answer 1

The correct option is D Lead to accumulation of pesticide residues in body fat.

In India, prolonged use of 0.02-13 ppm of DDT (pesticide) can be detected in the body fat of the people. Most toxic pollutants such as pesticides do not degrade easily and therefore accumulate within the body of an organism specially in fat deposited portion. This process is known as biochemical concentration.

Therefore, the correct answer is option D.
