Answer:
C) price ceiling
Step-by-step explanation:
Price ceiling is the price control or the limit which is imposed by the government on how high the price can be charged for the particular commodity, product, or service.
Governments often use price ceilings in order to protect the consumers from conditions which could make the commodities prohibitively expensive.
