Answer:
B. To enable rationing
Step-by-step explanation:
The purpose of price ceiling would be to enable rationing.
A price ceiling represents an imposed price control over a product. It is the maximum amount a manufacturer or a supplier is allowed to charge for a product within an economy.
Price ceilings are imposed so as to ensure that prices of products remain within the range of an average consumer within a population and prevent excessive upward movement of prices.
Price ceilings help in rationing. It ensures that an average consumer is not overcharged for products in as much as the manufacturer/suppliers get reasonable profit for their production.
