    B P = MC Correct Answer Incorrect Answer
    C P < AC Correct Answer Incorrect Answer
    D All of these Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    While a monopolistic competitive firm can make a profit in the short-run, the effect of its monopoly-like pricing will cause a decrease in demand in the long-run. This increases the need for firms to differentiate their products, leading to an increase in average total cost. The decrease in demand and increase in cost causes the long run average cost curve to become tangent to the demand curve at the good’s profit maximizing price. This means two things. First, that the firms in a monopolistic competitive market will produce a surplus in the long run. Second, the firm will only be able to break even in the long-run; it will not be able to earn an economic profit. In the long-run, a monopolistically competitive market is inefficient. It achieves neither allocative nor productive efficiency.
