    are mats.   Conclusion: I. Some dogs are mats. II. All dogs can never be mats.
    A Only conclusion II follows. Correct Answer Incorrect Answer
    B Only conclusion I follows. Correct Answer Incorrect Answer
    C Neither conclusion I and II follow. Correct Answer Incorrect Answer
    D Either conclusion I or II follow. Correct Answer Incorrect Answer
    E Both conclusion I and II follow. Correct Answer Incorrect Answer

    Solution

    No dog is a cat (E) + All cats are mats (A) → Some mats are not dogs (O*). Hence neither conclusion I nor II follows but it will make a complementary pair. Hence either conclusion I or II follows.
