a. better satisfies customer needs than rival products do.

Explanation:

Product differentiation is the process by which a product is made to be different from what other competitors are offering. This is done to better satisfy a target market. Product differentiation can also occur within a firm to differentiate it from other firm offerings.

For example if a company decides to put a torch light on a pen. This will diffentiate the product from other pens in the market and will give customer more satisfaction by providing the extra service of lighting.
