The least possible Venn Diagram for the given statements is drawn below:
Conclusions:
I. No E is A → True (As no D is E, and all A are D, so, no E is A is also true.)
II. All D are A → False (It is possible, but no definite conclusion can be drawn.)
III. All E are D → False (As no D is E so, all E can never be D.)
