Which of the following is NOT considered a category killer?

The concept of a "category killer" refers to a large retail chain that dominates a particular segment of the market, typically offering an extensive selection of products within that category at competitive prices. These stores often drive out smaller competitors due to their buying power and efficiency.

In this context, Best Buy, Home Depot, and Lowe's are all considered category killers. Best Buy is a leader in consumer electronics, while Home Depot and Lowe's dominate the home improvement and construction materials sector. They cater specifically to their market niches with a broad selection and often undersell smaller competitors.

Target, while a large retail chain, is classified more as a general merchandise retailer rather than a category killer. It sells a wide range of retail goods, including groceries, clothing, and household items, rather than focusing exclusively on one specific category. This diversification allows Target to compete in various segments without overwhelming market dominance in a single category, hence it does not fit the category killer definition, making it the correct answer.
