Answer:
C-market value of final goods and services
Step-by-step explanation:
When the total spent by consumers on the purchase of a good or service equals the total received by the providers of goods and services, the economy will be in balance. The selling price will be the equilibrium price and the traded quantity will be the equilibrium quantity. This is the market adjustment mechanism, where supply is said to be equal to demand.
For example, if there is an offer of 100 units of a product and a demand of 100 units as well, then these 100 units will be the equilibrium quantity (since the total supply satisfies all the demand). The purchase price will be spent by consumers and captured by the providers.
