Answer:
The correct answer is option D.
Step-by-step explanation:
Total surplus is also known as economic surplus and is the sum of consumer surplus and producer surplus.
Consumer surplus can be defined as the difference between total amount the consumer is willing to pay and the price it has to pay actually.
Producer surplus can be described as the difference between the amount a supplier is willing to accept and the amount it actually gets.
The total surplus can be calculated through the total value of the good to buyers minus the cost to sellers of providing the good.
