    B Only conclusion I follows Correct Answer Incorrect Answer
    C Only conclusion III follows. Correct Answer Incorrect Answer
    D Both conclusion I and II follow Correct Answer Incorrect Answer
    E None follows Correct Answer Incorrect Answer

    Solution

    Only few stems are roots →   Some stems are roots (I) and Some stems are not roots (O). Hence conclusion I does not follow. Some windows are stems (I) + Some stems are roots (I) → No conclusion. Hence conclusion II does not follow. No door is a window (E) + Some windows are stems (I) → Some stems are not doors (O*) → Probable conclusion → All stems may not be doors (I). Hence conclusion III does not follow.
