    C Only conclusion II follows Correct Answer Incorrect Answer
    D Only conclusion III follows Correct Answer Incorrect Answer
    E None of the conclusion follows Correct Answer Incorrect Answer

    Solution

    Only constellation are universe → All universe are constellation and universe cannot have any positive relation with any element. Hence conclusion I does not follow. Some planet are constellation (I) → Conversion → Some constellation are planet (I). Hence conclusion II does not follow. Some planet are constellation (I) + 15% constellation are star → No conclusion. Hence conclusion III does not follow.
