The least possible Venn Diagram for the given statements is drawn below:
Conclusions:
I. All yellow are roses → False (It is possible, but no definite conclusion can be drawn.)
II. Some buses are yellow → True (As some yellow are buses, so, some buses are yellow is also true.)
III. All yellow are green → False (It is possible, but no definite conclusion can be drawn.)
