Answer: a. is the difference between the maximum prices consumers are willing to pay for a product and the lower equilibrium price
Explanation:
Consumer surplus is known to be the differences between the amounts consumers are ready and able to purchase and pay for a good and the market price which the consumers are charged to pay for the good. It is represented on the demand curve by the area under it which is at the top of the equilibrium price. Thus, it is of great benefit to consumers because they buy products for lesser prices in the market than the prices which they are expecting to pay for the products.
