What does supply refer to?

• A. How much is available
• B. Demand level
• C. Price
• D. Production rate

Answer: (A)

Supply is about the quantity of a good that producers are willing and able to offer for sale at various prices over a specific period. The description “how much is available” directly captures that idea because it refers to the amount that can be offered to the market at different prices. Price influences how much is supplied, but it’s not the definition of supply itself. Demand level describes what buyers want to purchase, not what sellers are willing to provide. Production rate can affect supply, but the standard concept of supply is the amount available to the market at each price, given producers’ willingness and ability to produce.
