What is defined as two or more stores under the same ownership or identity?

The correct answer is chain. A chain is characterized by having multiple retail establishments that share the same ownership and typically operate under a unified brand or identity. This format allows for greater consistency in customer experience, marketing strategies, and often bulk purchasing advantages, which can lead to cost savings and lower prices for consumers. Chains can offer a range of products or services and are commonly found in various sectors, including food, clothing, and electronics.

The other options represent different types of retail structures: an outlet store usually refers to a discount retailer that sells surplus or discontinued stock from a specific brand, often at reduced prices. A franchise involves an independent entity that operates using the brand and business model of a larger company but is not under the same ownership; the franchisee pays for the right to operate under the franchisor's brand. An independent retailer operates a single store that is not affiliated with any larger chain or franchise, giving it a unique identity but without the benefits that can come from being part of a chain.
