The money used to buy groceries primarily serves as a medium of exchange. Here's a detailed explanation:

1. Medium of Exchange: This is the primary function of money that facilitates transactions for goods and services. When you buy groceries, you are using money to exchange for food, which makes it a medium of exchange.

2. Reserve of Wealth: While money can store value, in this context, the act of using money to purchase groceries does not represent storing wealth; it's actively being spent.

3. Unit of Account: Money is also a unit of account because it provides a standard measurement of value. However, in the context of buying groceries, you are not using money to measure value but rather to make a purchase.

4. Store of Value: Money does maintain value over time, but again, the act of buying groceries is a transaction rather than storing value.

Thus, the correct answer is medium of exchange.
