The correct answer is C. A ten dollar bill can purchase a five dollar item, with five dollars change coming back.
Divisibility in the context of money means that it can be easily divided into smaller units, facilitating transactions of various sizes. In this example, a ten dollar bill can be used to purchase an item worth five dollars, and the change of five dollars can be given back.
This demonstrates the divisible nature of money, allowing for flexibility in transactions of different amounts.
