Most of the markets are imperfectly competitive. The extreme cases of imperfect competition are monopoly and monopsony. Monopoly is a market where there is only one seller.

The Türk Telekom, for example, is a monopoly in internet infrastructure. All the other internet providers have to use Telekom’s infrastructure. Likewise, TCDD is a state owned monopoly in railway transportation. There are also local monopolies. Many cities in Turkey are served by a single airline (typically THY subsidiary Anadolu Jet). In smaller towns, many goods and services could be offered by a single seller. There are a few worldwide monopolies as well: SpaceX, for example, is the only company selling touristic trips to the space. The pricing behavior of a monopoly is totally different than the behavior of firms operating in a competitive market. Monopsonist markets are the ones in which there exist only one buyer and many sellers. The relatively high agricultural prices in Turkey might be attributed to near monopsonist local markets where there are only a few merchants buying the farmers’ products. For example, larger milk and dairy product firms generally act as monopsonist buying wholesale milk from cow owners in many towns around Turkey.

As it is understood from the information given the correct answer is “B”.
