The least possible Venn Diagram for the given statements is drawn below:
Conclusions:
I. No bulb is a tube → False (It is possible but no definite conclusion can be drawn.)
II. Some tumblers are bulbs → True (As some bulbs are tumblers, so, some tumblers are bulbs is also true.)
Hence, Only conclusion II follows.
