• A. 2005
• B. 2004
• C. 2007
• D. 2009

Hint:

ISBN's 13-digit structure enhances book tracking and inventory systems.

Answer 1

The Correct Option is C

The International Standard Book Number (ISBN) system shifted from a 10-digit to a 13-digit format in 2007. This change aligned ISBN with the Global Trade Item Number (GTIN) system to integrate with international EAN barcode systems used in retail. The new structure improves global compatibility for book identification.
