Result
Your answer: —  Â·  Correct: B
Explanation

The classification of market structures is based on the number of producers and product nature. Perfect competition (A) is characterized by many producers selling identical or similar products where firms are price-takers [1]. A monopoly (B) exists when there is only one producer selling a unique commodity with no close substitutes. Monopolistic competition (C) involves many producers selling differentiated products that are close substitutes but not identical. Finally, an oligopoly (D) is defined by a few large producers selling either similar or differentiated products, where the actions of one firm significantly impact others. Matching these characteristics: A-4 (Many/Similar), B-1 (One/One commodity), C-3 (Many/Differentiated), and D-2 (Few/Similar). This corresponds to option 2.
