Answer:
The correct answer is (A)
Step-by-step explanation:
Demand and supply curves are used to determine the equilibrium price and quantity. A sudden change in the price level will affect the equilibrium point because the price level will affect the demand curve. An increase in the price level will shift the demand curve to the left. The demand curve will shift downwards because people will have to pay more money to buy the same products, so they will buy less.
