Which of the following is an example of a shopping center?

A shopping center is a designated area where various retail businesses are located, designed to provide customers with a convenient shopping experience. A mall is a prime example of a shopping center as it typically includes multiple stores, restaurants, and services all housed under one roof or within a defined perimeter, allowing customers to browse and shop without needing to travel to different locations.

In contrast, a warehouse is primarily focused on storage and distribution rather than retail shopping experiences. An online retailer operates on the internet, which does not involve a physical shopping center; it allows consumers to shop virtually without a physical presence. A convenience store, while it offers retail shopping, is generally a standalone store rather than part of a shopping center, lacking the collective shopping environment that defines a shopping center like a mall. Thus, a mall is the correct answer as it embodies the characteristics of a shopping center.
