Answer
Both A and R are true but R does not explain A.
Explanation — Chemical fertilisers contain plant nutrients such as nitrogen, phosphorous and potassium. These fertilisers are used to enrich the soil, but they also contaminate the soil with their impurities. When the fertilisers are contaminated with other synthetic organic pollutants, the water in the soil gets polluted too. Hence, excessive use of chemical fertilisers creates pollution.
