C. Offering identical products to consumers
D. Offering products that are similar but not identical
Explanation
In monopolistic competition, product differentiation refers to offering products that are similar but not identical.
This means that firms produce goods or services that are slightly different from those of their competitors, allowing them to distinguish their products in the market.
Product differentiation can take various forms such as branding, quality, design, or customer service.
