    C Only conclusion III follows. Correct Answer Incorrect Answer
    D Both conclusion II and III follow. Correct Answer Incorrect Answer
    E None of the above. Correct Answer Incorrect Answer

    Solution

    Only few Comets are Constellation → Some Comets are Constellation (I) and Some Comets are not Constellation (O). Hence conclusion I does not follow. All Planets are Satellites (A) + Some Satellites are Comets (I) → No conclusion. Hence conclusion II does not follow. Some Satellites are Comets (I) + Some Comets are Constellation (I) → Probable conclusion → Some Satellites are Constellation (I) + No Constellation is a Meteors (E) → Some Satellites are not Meteors (O) → Probable conclusion → Some Satellites meteors be Meteors (I). Hence conclusion III follows.
