Only constellation are universe.

15% constellation are star.

II. All planet are constellation.

III. No star is planet.

A Both conclusion I and conclusion II follow. Correct Answer Incorrect Answer
B Only conclusion I follows Correct Answer Incorrect Answer
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.
