Step-by-step explanation:
Joanna’s decision to contribute a share of her profits each year to support cancer research as her fast-food chain becomes more successful is an example of cause-related marketing. Cause-related marketing refers to a type of marketing where a company decides to support a specific cause and commits to a partnership that benefits both the cause and the company. This practice can enhance a company's image, build consumer loyalty, and increase sales, all while supporting a good cause. In Joanna's case, it also shows her business's commitment to corporate community involvement, although that is not the primary focus of her activity in this context.
The answer to the question is C) cause-related marketing.

In this case, Joanna's decision to contribute a share of her profits to support cancer research aligns with cause-related marketing. This strategy allows her to give back to the community and promote her fast-food chain at the same time.
