The correct answer is: A. Below the demand curve and above the price line.
The area of consumers savings is the area below the demand curve and above the price line. This area represents the amount of money that consumers save when the price of a good or service falls.
The demand curve shows the relationship between the price of a good or service and the quantity demanded. The price line shows the current market price of the good or service. The area below the demand curve and above the price line represents the amount of money that consumers would be willing to pay for the good or service, but are not actually paying because the price is lower.
For example, if the demand curve is D and the price line is P, the area of consumers savings is the shaded area. This area represents the amount of money that consumers save because the price of the good or service is P instead of some higher price.
The area of consumers savings is a measure of the benefit that consumers receive from a decrease in the price of a good or service. This benefit is called consumer surplus.
