Perfect competition exists under which condition?

Perfect competition exists under which condition?

• A. Free and open competition
• B. Government-controlled pricing
• C. High barriers to entry
• D. Sole supplier

Answer: (A)

Perfect competition hinges on many buyers and sellers freely trading a homogeneous good with no artificial hurdles to entry or exit. When trades occur in such an open, competitive environment, no single firm can set the price—they take the market price as given and produce where price equals marginal cost, leading to efficient allocation of resources. Government-set prices disrupt price-taking behavior, high barriers to entry block new competitors, and a sole supplier creates a monopoly—none of these fit perfect competition.
