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 ships being windows is a possibility → True (As some ships are cups, and all windows are cups, so, some ships being windows is a possibility is also true.)
II. No window is a stool → True (As all windows are cups, and no cup is a stool, so no window is a stool.)
III. All cups are windows → False (It is possible, but no definite conclusion can be drawn.)
IV. No ship is a stool → False (It is possible, but no definite conclusion can be drawn.)
