    B Only II follows Correct Answer Incorrect Answer
    C Only II and III follow Correct Answer Incorrect Answer
    D None follows Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    All frocks are skirts (A) ⇒ Conversion ⇒ Some skirts are frocks(I). Hence conclusion I does not follow. No pant is a frock(E) + All frocks are skirts(A) ⇒ Some skirts are not pants(O*). Hence conclusion II follows. Some dresses are pants(I) + No pant is a frock(E) ⇒ Some dresses are not frocks(O). Hence conclusion III does not follow.
