Answer:
The correct answer is option C.
Explanation:
A monopolistic market is a form of market where there is a large number of producers who are producing close substitutes. There are few barriers to entry in the market, but it is easier to enter as compared to other imperfect markets. Â
Monopolistic firms face a downward-sloping demand curve. They are not price takers and don't need to produce at the minimum ATC in the long run like a firm in a perfectly competitive market.
So, option C is the correct answer.
