need help with this question..

Are monopolistically competitive firms efficient in long-run equilibrium? Monopolistically competitive firms O A. are not productively efficient because they do not produce at minimum average total cost and they are not allocation efficient because they produce where price is greater than marginal cost. O B. are not productively efficient because they do not produce at minimum marginal cost and they are allocationy efficient because they produce where marginal cost equals marginal revenue. O C. are not productively efficient because they do not produce at minimum marginal cost and they are not allocationy efficient because they produce where price is less than marginal revenue. O D. are not productively efficient because they do not produce at minimum average total cost and they are allocationy efficient because they produce where price is less than marginal cost. O E. are productively efficient because they produce at minimum average total cost and they are allocationficient because they produce where price is less than marginal revenue
