Answer:
I, II and III.
Explanation:
Price ceiling refers to the price control policy that is used by the government to protect the customers who are not able afford goods at the prevailing price.
If government of a nation sets a price ceiling below the equilibrium price level then this will increase the quantity demanded for the product because now goods become more affordable to the consumers and decreases the quantity supplied because it will become less profitable for the producers.
Hence, the demand for goods exceeds the supply of goods, this will create a shortage of goods in an economy.
