Step 1: Understanding the Concept:
Market structures are classified based on the number of participating firms, their degree of control over price, barriers to entry, and the homogeneity or differentiation of their products.
Step 2: Detailed Explanation:
Let us match each market structure in List-I with its defining characteristics in List-II:
- (A). Perfect Competition:
This market has a very large number of buyers and sellers.
All sellers produce identical, homogeneous products.
Firms are price takers.
This matches with (III) Large number of firms; products are homogeneous.
- (B). Monopolistic Competition:
This market has a large number of relatively small sellers.
Products are differentiated through branding, packaging, or features, but are close substitutes for one another.
This matches with (IV) Large number of firms; products are differentiated with close substitutes.
- (C). Oligopoly:
This market is dominated by a few large firms.
The products may be homogeneous (pure oligopoly) or differentiated (differentiated oligopoly).
Firms exhibit high strategic interdependence.
This matches with (I) Few firms; products may be homogeneous and differentiated with close substitutes.
- (D). Monopoly:
This market structure has only one firm representing the entire industry.
The firm produces a unique product with no close substitutes.
This matches with (II) One firm; unique product without close substitutes.
Thus, the correct matching is: (A) - (III), (B) - (IV), (C) - (I), (D) - (II).
Step 3: Final Answer:
The correct option is (D).
