The least possible Venn Diagram for the given statements is drawn below:
Conclusions:
I. Some ducks are chickens → False (As all bananas are avocados, so, some avocados are bananas is also true.)
II. Some hens are ducks → True (As some ducks are hens, so, some hens are ducks is also true.)
Hence, Only conclusions I and III follow.
