• A.
• B.
• C.
• D.

Hint:

When working with logical reasoning, carefully analyze the relationship between the set elements and ensure that conclusions align with the given statement without contradiction.

Answer 1

The Correct Option is C

Given the statement "No book is copy," it means there is no overlap between the set of books and the set of copies. Let's analyze the conclusions: - Conclusion 1: "No copy is book" - This conclusion is true because if no book is a copy, then it must follow that no copy is a book. - Conclusion 2: "Some copies are not books" - This conclusion is true because if no book is a copy, then it is clear that some (or all) copies are not books. - Conclusion 3: "All books are not copies" - This conclusion is true because the statement explicitly says "no book is copy," meaning all books are not copies. - Conclusion 4: "All books are copies" - This conclusion is false because the statement clearly says "no book is copy," contradicting the idea that all books are copies. Thus, Conclusions 1, 2, and 3 are true, and the correct answer is (C).
