    C Only I, and either II or III follow Correct Answer Incorrect Answer
    D Only I and II follows Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    All cups are bowls(A) + All bowls are trays(A) → All cups are trays(A) → conversion → Some trays are cups(I). Hence, conclusion I will follow. A + I → No conclusion. Hence, neither conclusion II nor III will follow but they will make a complementary pair. Hence, either conclusion II or III will follow.
