    Read the passage carefully and answer the questions:
    Soil pollution comprises the pollution of soils with materials, which may have adverse effects on humans or other organisms. It is difficult to define soil pollution exactly because different opinions exist on how to characterise a pollutant; while some consider the use of pesticides acceptable if their effect does not exceed the intended result, others do not consider any use of pesticides or even chemical fertilisers acceptable. However, soil pollution is also caused by means other than the direct addition of xenobiotic (man-made) chemicals such as agricultural runoff waters, industrial waste materials, acidic precipitates, and radioactive fallout.
    What do you mean by xenobiotic?

    A) It is man made chemical

    B) It causes soil pollution

    C) It is harmful for soil

    D) All of these

    E) None of these
