    A Only I and III follow Correct Answer Incorrect Answer
    B Only II follows Correct Answer Incorrect Answer
    C Only II and either I or III follow Correct Answer Incorrect Answer
    D Only III follows Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Some rectangle are squares (I) → Probable conclusion → All squares may be rectangle (A). Hence conclusion I follows. Some cube are triangle (I) → Conversion → Some triangle are cube (I). Hence conclusion II does not follows. Some cube are triangle (I) → Conversion → Some triangle are cube (I) + Some cube are squares (I) → Probable conclusion → Some triangle are squares (I) + Some squares are rectangle (I) → Probable conclusion → Some rectangle can be triangle (I). Hence conclusion III follows.
