D, visiting the same barber out of many in the city because you like the way he cuts hair.
Explanation:
Monopolistic competition is one in which firms produce the similar products but have brand loyalty from its various consumers.
In monopolistic competition, the production of similar goods by firms doe not make the products a substitute for the other.
Monopolistic competitions allows for a large number of buyers and sellers, low entry or exit barriers, etc.
The visitation of a particular barber despite having other barbers in town is an example of brand loyalty which is in turn a characteristic of monopolistic competition.
