    C Only conclusion I follows Correct Answer Incorrect Answer
    D Only conclusion II and conclusion III follow. Correct Answer Incorrect Answer
    E None follows. Correct Answer Incorrect Answer

    Solution

    No Harpic is Pesticide (E) → Conversion → No Pesticide is Harpic (E) + Only a few Harpic is Lizol (I) → Some Lizols are not Pesticides (O*) → Probable conclusion → All Pesticide can be Lizol (A). Hence conclusion I follows. No Harpic is Pesticide (E) → Conversion → No Pesticide is Harpic (E) + Only a few Harpic is Lizol (I) → Some Lizol are not Pesticide (O*). Only a few Lizol is Detergent (I) + Some Lizols are not Pesticides (O*) → No conclusion. Hence conclusion II does not follow. Only a few Harpic is Lizol (I) + Only a few Lizol is Detergent (I) → Probable conclusion → Some Detergents can be Harpics (I). Hence conclusion III follows.
