    B None of the conclusions follow Correct Answer Incorrect Answer
    C Only conclusion I follows Correct Answer Incorrect Answer
    D Both conclusions I and II follow Correct Answer Incorrect Answer

    Solution

    Some Pencils are Chalk (I) → Conversion → Some Chalk are Pencils (I) + All Pencils are Board (A) → Some Chalk are Board (I) → Conversion → Some Board are Chalk (I) + No Chalk is Desk (E) → Some Board are not Desk (O). Hence conclusion I follows.

    Some Pencils are Chalk (I) + No Chalk is Desk (E) → Some Desk are not Pencils (O*). Hence conclusion II does not follow.
