A Correct answer
Explanation

Like all profit-maximizing firms regardless of market structure, a monopolistically competitive firm produces where Marginal Revenue equals Marginal Cost (MR = MC). At this output level, the firm maximizes its profit or minimizes its loss. The other options (MR > MC would mean underproducing, MR < MC would mean overproducing) represent suboptimal decisions.
