Step 1: Understanding monopolistic competition.
Monopolistic competition is a market structure in which many firms sell similar but not identical products. It arises when firms offer differentiated products, which means that the goods are non-homogeneous.
Step 2: Analyzing the options.
(A) Due to homogeneous good: This option refers to perfect competition, not monopolistic competition, as homogeneous goods are identical across firms.
(B) Due to non-homogeneous good: Correct. Monopolistic competition arises when firms sell differentiated products, meaning the goods are non-homogeneous.
(C) Due to perfect substitute goods: This would refer to perfect competition where products are substitutes for each other.
(D) None of these: This is incorrect because the correct answer is (B).
Step 3: Conclusion.
Monopolistic competition arises when firms sell differentiated products, meaning the goods are non-homogeneous. Therefore, the correct answer is (B) Due to non-homogeneous good.
