Which of the following is NOT one of the elements of the marketing mix?

The correct answer is "People" because the traditional elements of the marketing mix, often referred to as the "4 Ps," include Product, Place, Price, and Promotion. Each of these elements plays a crucial role in the development and execution of a marketing strategy.

In this context, "Product" refers to the goods or services that satisfy customers' needs; "Place" denotes the distribution channels used to deliver the product to consumers; and "Promotion" encompasses the various tactics employed to communicate with potential customers about the product, including advertising, sales promotions, and public relations.

While "People" is an important aspect of marketing, especially in service industries where customer interaction is vital, it is not specifically part of the traditional marketing mix framework. Instead, it could be considered an extension or an important factor that influences other aspects of the marketing strategy, particularly in services marketing, where the involvement of staff can significantly affect customer satisfaction and experience.
