Step 1: Understanding the Concept:
A monopoly is a market structure characterized by a single seller or producer of a commodity that has no close substitutes.
Analyzing the level of competition, product characteristics, and elasticity of demand helps distinguish a monopoly from other market structures like perfect competition or monopolistic competition.
Step 2: Detailed Explanation:
Let us evaluate the characteristics of a monopoly market:
1. Single Seller:
In a monopoly, there is only one firm producing and selling the product.
Because there are no other firms in the market, there is a complete absence of competition (Option B).
Therefore, this statement is correct.
2. No Close Substitutes:
The product sold by a monopolist has no close substitutes.
Because there are no similar competing products, the cross-elasticity of demand between the monopolist's product and any other product is zero or very low (not very high, Option D).
3. Barriers to Entry:
Strong legal, natural, or institutional barriers prevent new firms from entering the market, maintaining the absence of competition.
4. Homogeneous vs Heterogeneous Product:
Product differentiation (heterogeneity, Option C) is a characteristic of monopolistic competition, where many firms sell similar but slightly different products, which is not applicable to a monopoly.
Step 3: Final Answer:
A monopoly market is characterized by a single seller, resulting in a complete absence of competition.
Therefore, the correct option is (B).
