Final answer:
CVS, known for selling prescription medicines along with a smaller selection of items like greetings cards and cosmetics, is correctly classified as B) Drugstore.
Step-by-step explanation:
The question asks which major type of retail operations CVS can be classified as. Given that CVS focuses its product sales on prescription medicines, greetings cards, and cosmetics, the correct classification would be B) Drugstore.
Major grocery stores, as described, offer a wide range of food products and are organized into various food-related departments, characterizing them as supermarkets, which does not precisely fit CVS's business model.
On the other hand, department stores like Sears, historically served by mail-order catalogs featuring a broad assortment of general merchandise, also do not align with CVS's focused offerings. CVS fits the drugstore category because it specializes primarily in pharmaceuticals and also sells a limited selection of non-prescription items such as greetings cards and cosmetics.
