The least possible Venn Diagram for the given statements is drawn below:
Conclusions:
I. Some books are pens → False (It is possible, but no definite conclusion can be drawn.)
II. Some novels are pens → False (It is possible, but no definite conclusion can be drawn.)
III. No book is a pen → False (It is possible, but no definite conclusion can be drawn.)
Conclusion I and III makes a complementary pair. Hence, Either conclusion I or III follows.
