Which type of store sells a wide variety of goods, including food, alcohol, and medicine?

The option of supermarkets is the correct choice because supermarkets are specifically designed to offer a wide variety of goods, including essential items such as food, beverages (including alcohol), and household products like medicine. They typically feature a large selection of grocery items alongside non-food products, catering to a diverse range of consumer needs.

Supercenters, while they do offer a wide variety of goods, extend beyond groceries to include general merchandise and a breadth of categories such as clothing and electronics, which makes them more of a hybrid model.

Department stores generally focus on apparel, home goods, and other non-grocery items. They do not specialize in food or medicine to the same extent as supermarkets do.

Convenience stores offer limited food items and essential goods, typically focusing on convenience and accessibility rather than a comprehensive range of products. Their selection of food and other essentials is much narrower compared to what supermarkets provide.

Therefore, supermarkets stand out as the designated type of store that encompasses a wide variety of products, including food and essentials like alcohol and medicine.
