The options for this question are the following:

A. a cartel, as the three airlines together would attempt to coordinate policies in the local market to jointly maximize profits.

B. monopolistic competitors, as each firm would have to differentiate its airline services from its rivals.

C. perfect competitors, as each firm would sell travel services at the same fares as the other airlines.

A cartel is the formal expression of a collusion agreement. This implies that firms explicitly agree on the level of certain competitive variables such as price, quantity, distribution of customers or areas, etc.

The goal of cartel members is to increase joint benefits at the cost of reducing or eliminating competition. In this way, it is intended to act as a monopoly by increasing prices, reducing the quantity and increasing the profits obtained from sales.
