Step-by-step explanation:
Monopolistically competitive industries offer benefits to consumers through product differentiation. Product differentiation is based on variety and innovation, providing consumers with a wide range of choices. This allows firms to attract customers through methods like friendlier service, free delivery, guarantees of quality, variations on existing products, and a better shopping experience. The competition among firms to differentiate their products ultimately benefits consumers by providing them with more options and improved offerings.
