Which of the following is correct?

A) Money is a resource, but real capital is not.
B) Real capital is a resource, but money is not.
C) Neither money nor real capital is a resource.
D) Both money and real capital are resources.

Real capital refers to physical assets like machinery, buildings, and equipment used in production, which are considered resources in economics. Money, however, primarily serves as a medium of exchange, a unit of account, and a store of value, and is not considered a resource in the same way, as it does not directly contribute to production.
