Final answer:
Annie's Organic Shells & White Cheddar is a convenience product because it is purchased frequently and readily available, distinguishing it from shopping, specialty, and unsought products.
Step-by-step explanation:
Annie's Organic Shells & White Cheddar, an organic macaroni and cheese product, is an example of a convenience product. Convenience products are those that are purchased frequently, with minimal effort and primarily out of need rather than any unique preference. These products are widely available and often recognized by brands. In contrast, a shopping product is one for which consumers compare various attributes like quality, price, and style. A specialty product is a unique item for which consumers will make a special effort to search and purchase, while an unsought product is one that the consumer does not know about or does not normally think of buying.
