    B Only Conclusions I and III follows Correct Answer Incorrect Answer
    C Only Conclusion III follows Correct Answer Incorrect Answer
    D Only Conclusion II follows Correct Answer Incorrect Answer

    Solution

    All Apples are Mango (A) →I.I. → Some Apples are Mangoes (I). Hence conclusion I follows. Some Oranges are Apples (I) + All Apples are Mangoes (A) → Some Oranges are Mangoes (I) + No Mango is Pear (E) → Some Oranges are not Pear (O). Hence conclusion II does not follows. All Apples are Mangoes (A) + No Mango is Pear (E) → No Apples is Pear (E) → Conversion → No Pear is Apples (E). Hence conclusion III follows.
