A Correct answer
Explanation

ISBN stands for 'International Standard Book Number', a unique identifier used for books. The other options incorrectly use 'Bed', 'Numericals', or 'Ball' instead of 'Book', or change 'Number' incorrectly. Every published book has an ISBN to help with cataloging and identification in libraries and bookstores.
