Monopoly
Step-by-step explanation:

"A monopolistic competitive industry has the following features:
Many firms.
Freedom of entry and exit.
Firms produce differentiated products.
Firms have price inelastic demand; they are price makers because the good is highly differentiated
Firms make normal profits in the long run but could make supernormal profits in the short term
Firms are allocatively and productively inefficient."
