Which statement describes a perfectly competitive market?

• A. Many buyers and sellers, identical products, free entry; price takers.
• B. A single seller with price setting power.
• C. Government ownership of all firms.
• D. High barriers to entry and product differentiation.

Answer: (A)

In a perfectly competitive market, there are so many buyers and sellers that no one can influence the price. The goods are identical, so consumers don’t care which seller they buy from. Free entry and exit mean new firms can join when profits look good and can leave if profits vanish, keeping overall profits driven to normal in the long run. Because each firm is a small part of a large market, they are price takers—they accept the market price rather than setting it. The described statement captures all of this: many buyers and sellers, identical products, free entry, and price takers. The other options describe scenarios with a single seller or barriers to entry or product differences, which prevent the market from being perfectly competitive.
