Answer 1

The least possible Venn diagram is:

Conclusions:

I. All yellow are roses. → Does not follow (As, Some roses are yellow and Some yellow are buses → Some yellow are roses)

II. Some buses are yellow. → Follows (As, Some yellow are buses)

III. All yellow are green. → Does not follow (As, Some yellow are buses and All buses are green → Some yellow are green)

Hence, 'Only conclusion II follows' is the correct answer.
