Which example illustrates a project that enhances an existing product?

A software update for your computer effectively enhances an existing product by improving its functionality, performance, and security without changing its fundamental nature or introducing a new product entirely. Such updates might include fixing bugs, introducing new features, or optimizing user interfaces, all aimed at enhancing the user experience of the existing software. This is a clear demonstration of product enhancement because it preserves the original product while providing added value and improvements based on user feedback or technological advancements.

In contrast, other options such as launching a new product, redesigning a brand, or expanding into a new market may involve the introduction of new elements or changes that do not specifically enhance an existing product, but rather create new offerings or alter the brand’s image. Thus, the software update distinctly represents the process of enhancing an existing product.
