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

    Solution

    Some Circle are Square (I) → Conversion → Some Square are Circle (I) + No Circle is a Cuboid (E) → Some Square are not Cuboid (O) → Probable conclusion → Some Square may not be Cuboid (I). Hence conclusion I follows. Only Square are Rectangle → All Rectangle are Square and Rectangle cannot have any positive relationship with anyone. Hence neither conclusion II nor III follow.
