Money serves as a store of value, which signifies that it can be saved and retrieved in the future, maintaining its value over time. This characteristic allows individuals to hold money today and use it later to make purchases or settle debts, rather than needing to consume goods immediately. Holding money can provide security and flexibility, allowing for future planning and spending decisions.

In the context of the other answers, the perspective that money can only be used for immediate purchases entirely undermines the concept of saving and planning for future transactions. Representing only economic goods fails to recognize that money itself is a distinct entity, serving a broader purpose. As for the notion that money can only be exchanged for other currencies, this is a limited view that overlooks the role of money in facilitating a wide variety of transactions and serving as a method of saving value. Thus, the defining feature of money as a store of value aligns perfectly with the ability to be held for future use, rather than consumed immediately.
