For most firms, the major difference between accounting profit and economic profit is that a. accounting profit omits the salaries of managers, and therefore, it is generally greater than economic profit. b. explicit and implicit costs are included in the accounting profit while only explicit costs are included in economic profit. c. accounting profit is based on opportunity cost, whereas economic profit is based on market transactions. d. accounting profit does not consider the opportunity cost of the firm's equity capital in terms of foregone interest and, therefore, generally overstates economic profit.

The answer is D.

Explanation:

Accounting profit can be calculated as total revenue minus total cost(this total cost is called explicit cost). Explicit cost is the cost that are related to the production of goods and services or to the generation of revenue. For example, wages and salary, electricity, raw materials etc. Accounting profit does not consider implicit cost(opportunity cost). It only considers explicit cost. And because it doesn't consider implicit cost, economic profit will be overstated.

Economic profit can be calculated as total revenue minus (explicit cost plus implicit cost). Implicit cost is the cost of the forgone or alternative option. Implicit cost is the cost of the alternative that was not chosen. For example, a business has the option of either using its plant and machinery and this will generate $50,000 per year or renting it out at $45,000. And in the end the business opts for using the machinery at $50,000. The implicit cost here is the cost of renting it out at $45,000.

This implicit cost and explicit cost are considered in calculating economic profit.
