C.

Derived its value through government decree and widespread acceptance for payment

解释：

Solution

1. Incorrect because in major economies today, money is not convertible into any other commodity by law but is considered legal tender. Such money, which is not backed by a physical commodity, is known as fiat money.
2. Incorrect because fiat money is not convertible into a precious metal or any other commodity. It is money that has value solely because of the government's declaration and the general acceptance of it for transactions.
3. Correct because fiat money's value is based on the government's decree and the fact that people widely accept it as a means of payment for goods, services, and debt settlements.

Monetary Policy

•

A不正确,因为在主要经济体中，法律规定货币不能兑换成任何其他商品，但它被认为是法定货币。这种没有实物商品支持的货币被称为法定货币。

B不正确，因为法定货币不能兑换成贵金属或任何其他商品。货币之所以有价值，完全是因为政府的声明和人们对它的普遍接受。

C正确，因为法定货币的价值是基于政府的法令和人们广泛接受它作为支付商品、服务和债务结算的一种手段的事实。
