Coins' Durability as Money

Steps:

• Recall the functions of money: medium of exchange, unit of account, store of value.
• Identify key properties: durability, portability, divisibility, recognizability.
• Compare coins and paper: coins last longer without wear.
• Select the advantage that enhances suitability for repeated use.

Why B is correct:

• Durability ensures money retains value over time, a core property for a store of value per economic definitions.

Why the others are wrong:

• A: Both coins and paper are divisible into smaller units.
• C: Visibility is similar for both in everyday transactions.
• D: Recognizability depends on design, not inherent to coins.

Final answer: B
