Answer:
The answer is A. the price offered by producers must be at or below the ceiling price
Step-by-step explanation:
A price ceiling is a limit on how high the price of product or service can be. Governments use price ceilings to protect consumers from the overbearing of producers. For example, let's say the price of rice in the market in going up daily as a result of scarcity. Government can set the price ceiling to be $20 per bag. This means that the price by bag must never go beyond $20. Producers can set their price to be at $20 or below $20 but must never go above the price ceiling ($20)
