Which of the following is an example of a product extension?

A product extension refers to the introduction of a new variant of an existing product, typically to broaden its appeal or reach a different segment of the market. In this context, releasing a new flavor of an existing snack brand is a classic example of product extension. It builds on the already established brand identity and customer loyalty while introducing something new to attract both existing and new consumers. This strategy not only revitalizes interest in the brand but also helps to capture additional market share by catering to diverse consumer preferences.

Changing the packaging of a product, launching a new advertising campaign, and offering discounts on an existing product represent other marketing strategies but do not equate to expansion of the product line itself. Instead, they focus on changes in presentation, promotion, and pricing, rather than the introduction of a new product variant. Thus, choosing to release a new flavor aligns perfectly with the definition of a product extension.
