Answer:
A: by serving as a tool for distributing goods and services
Step-by-step explanation:
Supply and demand x good determine the equilibrium price in the perfect competitive market. The equilibrium price is defined as the price that equals the quantities demanded by buyers and the quantities offered by sellers, so that both groups are satisfied.
Given that the appropriate solution to this shortage, which would be to raise the market price, is not possible because it is tabulated, there is no alternative but to administer the shortage.
