Question

Who owns the book on subject U? 

• A. B
• B. E
• C. D
• D. C
• E.

Hint:

Look for clues about positions (top, bottom) to eliminate incorrect options. Often, this will help identify who owns which book.

Answer 1

The Correct Option is C

1. B and A are explicitly excluded from owning the book on subject U.
2. C's book is already fixed at the top, so it cannot be at the bottom.
3. D's book is fixed at the bottom, matching subject U, so D must be its owner.

So, the correct answer is D.
