Correct option is B
The correct answer is (B) A, C, and E only
Explanation:
• Perfect competition is a theoretical market structure with specific characteristics.
• Feature C: There must be a very large number of buyers and sellers, such that no single participant can influence the market price (they are 'price takers').
• Feature E: Products are homogeneous, meaning the goods from different sellers are identical and perfect substitutes for each other.
• Feature A: Agricultural commodities like wheat, corn, and dairy products are the closest real-world examples of perfect competition.
• Why B and D are wrong: In perfect competition, there is freedom of entry AND exit (unlike statement B). Also, there is perfect information/knowledge sharing, meaning buyers and sellers know all prices and technology (unlike statement D).
Information Booster:
• In the long run, firms in perfect competition earn only 'normal profits'.
• The demand curve for an individual firm in perfect competition is perfectly elastic (horizontal).
• Marginal Revenue equals the market Price in this structure.
Additional Knowledge:
• Monopoly: Single seller, unique product, high barriers to entry.
• Monopolistic Competition: Many sellers, differentiated products (e.g., soaps, shampoos).
• Oligopoly: Few large sellers, interdependent decision making.
