Which of the following is typically included in discussions of product classes?

The focus on product classes includes the categorization of products based on specific characteristics and features, which often includes packaging. Packaging serves multiple purposes within product classes, such as attracting customers, providing information, enhancing product appeal, and differentiating products from competitors. It plays a crucial role in how products are perceived and marketed, making it a vital element in discussions surrounding various product categories.

In contrast, logistics, corporate structure, and supply chain management are related more to the operational and strategic components of marketing and distribution rather than the inherent features that define product classes. While these elements are important in the broader context of marketing, they do not specifically pertain to the classification of products based on their attributes.
