    B Only conclusions II and IV follow Correct Answer Incorrect Answer
    C Only conclusion II follows Correct Answer Incorrect Answer
    D Only conclusions I and IV follow Correct Answer Incorrect Answer

    Solution

    Some Trees are Roots (I) → I.I. → No conclusion. Hence conclusion I does not follow. Some Trees are Roots (I) + No Root is a Stem (E) → Some Trees are not Stems (O). Hence conclusion II follows. Some Petals are Flowers (I) + Only a few Flowers are Trees (I) → No conclusion. Hence conclusion III does not follow. Only a few Flowers are Trees → Some Flowers are not Trees (I). Hence conclusion IV follows.
