For commodity money to be effective, which characteristic is NOT required?

For commodity money to function effectively as a medium of exchange, it should possess certain essential characteristics. While options A, C, and D are critical attributes—ease of transport enables smooth transactions, divisibility allows for transactions of varying sizes, and durability ensures the money can withstand physical wear—the reliance on value derived from trust is not inherently a requirement for commodity money.

Commodity money is valuable in its own right because it is made of a substance that has intrinsic value, such as gold, silver, or other precious items. The value does not stem from the trust that people place in it as a currency, but rather from the actual material content. Therefore, while trust can certainly enhance the system in which commodity money operates, it is not a defining characteristic necessary for the effectiveness of commodity money itself. This distinct quality sets commodity money apart from fiat money, which relies heavily on trust and government backing to maintain its value.
