Answer:
C) The supply curve moved to the left.
Explanation:
A supply curve shift to the left due to a reduction in the quantity supplied to markets. When the market is at equilibrium, a decrease in supply will likely to create a shortage. Buyers will compete to buy the few available items at the price that suppliers will demand. Suppliers will take advantage of the " increase " in demand to raise prices.
A reduced supply means that the quantity available in the market decreases. At equilibrium, the quantity supplied matches demand, but when supply decreases, the quantity supplied also decreases.
