Answer:
The correct answer is option B.
Explanation:
Monopolistic competition is a market structure in which there is a large number of firms selling differentiated products which are close substitutes. Because of product differentiation, the firms are able to make their own prices.
A monopolistic competitive firm faces a downward-sloping demand curve. The firm is able to maximize profit by producing the output level where the marginal revenue is equal to marginal cost.
The price will be fixed above this point on the demand curve.
This profit-maximizing level of output is smaller than the socially optimal level and the price is higher than socially optimal. So a deadweight loss is created as resources are not allocated efficiently.
