IV. No stone is a glass.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Only Conclusions I and II follow.
The least possible Venn Diagram for the given statements is drawn below:
Conclusions:
I. Some stones being bats is a possibility → True (As some stones are cubes, and all bats are cubes, so some stones being bats is a possibility.)
II. No bat is a glass → True (As all bats are cubes, and no cube is a glass, so no bat is a glass.)
III. All cubes are bats → False (It is possible, but no definite conclusion can be drawn.)
IV. No stone is a glass → False (It is possible, but no definite conclusion can be drawn.)
