The reason "Bidirectional market" is the correct answer as the choice that is not a recognized type of market structure is that traditional economic theory recognizes four primary types of market structures: perfect competition, monopolistic competition, oligopoly, and monopoly.

Perfect competition describes a market with many buyers and sellers, where no single entity can influence prices. Monopolistic competition features many firms competing with slightly differentiated products. A monopoly exists when a single firm dominates the market, giving it significant control over pricing and supply due to the lack of competition.

In contrast, "Bidirectional market" does not correspond to any formally recognized market structure in economics. Instead, this term might refer more to a specific type of transaction mechanism or market behavior rather than an established classification of how markets operate. Therefore, it does not fit within the well-defined categories used to analyze market behavior and dynamics.
