Verified step by step guidance

1. Step 1: Understand the concept of 'product differentiation' in microeconomics. It refers to a strategy where a company offers different versions or variations of a product to distinguish itself from competitors and appeal to different consumer preferences.
2. Step 2: Recognize that 'perfect competition' involves many firms selling identical products, so no single firm can influence the market price, which contrasts with offering different versions of a product.
3. Step 3: Note that 'consumer surplus maximization' is an outcome related to consumer welfare, not a strategy for offering different product versions.
4. Step 4: Understand that 'price discrimination' involves charging different prices to different consumers for the same product, which is different from offering different versions of a product.
5. Step 5: Conclude that when a company offers different versions of a single product within a product category, it is practicing 'product differentiation' to target various consumer segments.
