Bundling and product differentiation are related concepts influencing the market dynamics of monopolistic competition. The correct answer to the question is: e. is the complete set of all products offered by a firm.
Step-by-step explanation:
The correct answer to the question is: e. is the complete set of all products offered by a firm. A product mix, also known as a product assortment, encompasses the total variety of products that a company offers for sale. It includes all different kinds of goods that a firm sells, including various product lines and individual product items within each line.
In contrast to a product mix, bundling involves selling two or more individual goods or services together as a combined package, often at a discount. This is seen commonly with cable companies offering a bundle of services such as the internet, cable TV, and phone service. Bundling can create added value for consumers who are looking to purchase multiple related services at once.
Furthermore, product differentiation plays a key role in monopolistic competition, where the variety of styles, flavors, and characteristics of products allows companies to compete in the market without necessarily needing to be the cost leader. This variety in offerings is part of what describes a company's product mix.
