In the model of monopolistic competition, if an industry has large relative to another industry, then we should expect firms to operate in a long-run equilibrium of that industry. A. marginal costs; less B. fixed costs; less C. marginal costs; more D. fixed costs; more

Option A:

Large Marginal costs; less firms in the industry

Explanation:

Monopolistic competitions are market models which are charaterized by low barriers to entry.  High marginal costs will discourage firms from entering the industry, thereby leading to a reduced number of firms operating there in the long run.

This makes Option C  the answer.
