The marketing manager of a breakfast cereal issues coupons to encourage purchase of the cereal.

Price refers to the amount of money consumers must pay to acquire a product or service. While the use of coupons may affect the perceived price by providing discounts, price itself is not a marketing function but rather a component of the marketing mix. Coupons do not change the fundamental price but serve as a tool to enhance promotional efforts.

Strategy is a broad term that encompasses an organization’s overall plan to achieve its goals and objectives. While the issuance of coupons can be part of a larger marketing strategy, it is not a marketing function in itself. Therefore, labeling the coupon issuance as merely "strategy" does not accurately address the specific marketing function being employed.

Distribution refers to the methods and processes used to make a product available to consumers. This includes logistics, supply chain management, and channel selection. Issuing coupons does not pertain to how the cereal is delivered to stores or how it reaches consumers; rather, it is a method of encouraging purchases once the product is available.
