Which action is least likely to positively influence a company's social responsibility strategy image rating?

The action of using celebrity endorsements for publicity is least likely to positively influence a company's social responsibility strategy image rating because it primarily focuses on marketing and brand visibility rather than genuine contributions to social or environmental causes. While celebrity endorsements can attract attention and may improve brand recognition, they do not necessarily reflect a company's commitment to social responsibility.

In contrast, implementing environmentally friendly practices demonstrates a commitment to sustainability, which directly enhances the company's image regarding social responsibility. Participating in charitable endeavors also reflects positively by showing that the company cares about social issues and is actively contributing to the community. Reducing product prices might aid in accessibility and affordability but does not inherently relate to social responsibility, thus making celebrity endorsements less relevant in this context.
