उत्तर
Both A and R are true, but R is not the correct reason for A.
Explanation:
Soil erosion lifts and releases fine soil particles (dust) into the air, producing particulate air pollution. The reason statement is also true: chemicals from fertilizers (nitrates, phosphates, pesticides) can dissolve or be carried by runoff and leach into groundwater. These are different processes (airborne dust vs. chemical leaching to water), so R does not explain A.
