Which of the following is an example of fiat money?

Fiat money is a type of currency that does not have intrinsic value and is not backed by a physical commodity, such as gold or silver. Instead, its value comes from the trust and confidence that people have in the government or authority that issues it. The Federal Reserve note, which is the paper currency used in the United States, is the best example of fiat money because it is accepted as a medium of exchange strictly based on the belief that it will be accepted by others in transactions.

In contrast, tobacco, gold, and hemp possess intrinsic value and have historically been used as forms of money or trade commodities due to their inherent properties. Tobacco has been used as a form of currency in various cultures, gold is a precious metal that has long been valued for its rarity and utility, and hemp can be used for a variety of practical purposes. While each of these materials can have value, they do not function as fiat money because they derive their worth from tangible properties rather than the backing of a government mandate.
