Answer:
The correct answer is option c.
Explanation:
The quota is a non-tariff restrictive barrier on trade imposed by importing countries. It is the quantitative limit fixed on the imports. When a quota is imposed below the equilibrium price. It will lead to a reduction in supply and cause an increase in price. This will increase producer surplus for domestic producers but reduce consumer surplus.
If a quota is imposed above the equilibrium quantity it will not affect the market. This is because the suppliers are already supplying less than the quota limit.
