Explanation:

Step1: Analyze each option

• 2 meters is too long for a book (a meter is about a yard, books are not that long).
• 20 meters is extremely long, way too big for a book.
• 2 centimeters is too short (about the width of a fingernail, books are longer).
• 20 centimeters is a reasonable length for a book (about the length of a standard ruler, which is a common book length).

20 centimeters
