What is true at the minimum efficient scale?Correct answer  The firm has achieved the lowest possible average cost of production.   Any increases in the scale of operation will encounter further economies of scale. You Answered  Marginal cost is at its minimum.   All possible economies of scale have not been exhausted.

At the minimum efficient scale, the firm has achieved the lowest possible average cost of production. This means that the firm is operating at a level where it is most efficient, producing its goods or services at the lowest cost per unit.

Any increases in the scale of operation will not necessarily encounter further economies of scale. Economies of scale refer to the cost advantages that a business obtains due to expansion. They are factors that cause the average cost of producing a good or service to fall as output increases. However, after reaching the minimum efficient scale, further increases in production may not lead to a decrease in the average cost per unit.

The statement "Marginal cost is at its minimum" is not necessarily true at the minimum efficient scale. Marginal cost refers to the cost of producing one more unit of a good or service. It can be at its minimum at any point, not necessarily at the minimum efficient scale.

The statement "All possible economies of scale have not been exhausted" is also not necessarily true at the minimum efficient scale. As mentioned earlier, after reaching the minimum efficient scale, further increases in production may not lead to a decrease in the average cost per unit. Therefore, it can be said that all possible economies of scale have been exhausted at the minimum efficient scale.
