Which of the following are features of a perfect competitive market?

(A) Free entry and exit of firms.

(B) Huge selling cost.

(C) perfectly elastic demand curve.

(D) perfect market knowledge among buyers.

Choose the correct answer from the options given below:

Solution

✅ Correct Option: 3

Option 1 -> Includes (B) which is incorrect as perfect competition has minimal selling costs, not huge ones.

Option 2 -> Includes (B) which is incorrect, and excludes (A) which is a fundamental feature of perfect competition.

Option 3 -> Correctly identifies (A), (C), and (D) as features of perfect competition while excluding (B).

Option 4 -> Incorrectly includes (B) which contradicts perfect competition principles.


Hence, Option 3: (A), (C) and (D) only -> In a perfectly competitive market, firms can freely enter and exit without barriers (A), each firm faces a perfectly elastic demand curve as they are price takers (C), and there is perfect information available to all market participants (D). However, huge selling costs (B) are NOT a feature of perfect competition - in fact, selling costs are minimal or zero because products are homogeneous and no advertising is needed. Selling costs are typically associated with monopolistic competition or oligopoly where firms try to differentiate their products -> correct
