Because this market is a monopolistically competitive market, you can tell that it is in long-run equilibrium by the fact that at the optimal quantity for each firm. Furthermore, the quantity the firm produces in long-run equilibrium is the efficient scale. True or False: This indicates that there is a markup on marginal cost in the market for jackets. True False Monopolistic competition may also be socially inefficient because there are too many or too few firms in the market. The presence of the externality implies that there is too little entry of new firms in the market.

Monopolistic competition has exclusive control over the means of production and prices. The frequency arises from the govt support.

In the long run, the monopolistically competition will make the market for the good where the long-run curve intersects the marginal revenue. This will lead to breakeven in in the longer run. Hence the option is true. The monopolistic competition may also create social inefficiencies as there too many firms.

Monopolistically competitive market in a long run detailed description is given below.

Explanation:

The difference between the short‐run and the long‐run in a monopolistically competitive market is that in the long‐run new firms can enter the market, which is especially likely if firms are earning positive economic profits in the short‐run. New firms will be attracted to these profit opportunities and will choose to enter the market in the long‐run. In contrast to a monopolistic market, no barriers to entry exist in a monopolistically competitive market; hence, it is quite easy for new firms to enter the market in the long‐run. The entry of new firms leads to an increase in the supply of differentiated products, which causes the firm's market demand curve to shift to the left. As entry into the market increases, the firm's demand curve will continue shifting to the left until it is just tangent to the average total cost curve at the profit maximizing level of output, At this point, the firm's economic profits are zero, and there is no longer any incentive for new firms to enter the market. Thus, in the long‐run, the competition brought about by the entry of new firms will cause each firm in a monopolistically competitive market to earn normal profits, just like a perfectly competitive firm. Excess capacity. a monopolistically competitive firm ends up choosing a level of output that is below its minimum efficient scale,When the firm produces below its minimum efficient scale, it is under‐utilizing its available resources. In this situation, the firm is said to have excess capacity because it can easily accommodate an increase in production. This excess capacity is the major social cost of a monopolistically competitive market structure.

Iwould say the answer is 4.
