Which organization offers a marketing challenge related to social impact?

Lead4Change offers a marketing challenge focused on social impact because it is dedicated to empowering student leaders to engage in community service and develop skills that enhance social responsibility. This organization encourages students to identify a social issue and create a project that not only addresses that issue but also fosters collaboration and leadership among peers. The emphasis on social impact aligns well with the mission of Lead4Change, making it the most appropriate choice among the options provided.

Social Media Marketing, Entrepreneurial Leadership, and Disability is Diversity contribute to marketing and leadership in different contexts but do not specifically focus on a structured marketing challenge aimed at social impact as Lead4Change does. These organizations may have other initiatives or programs, but they do not encapsulate the same focused approach to addressing social issues through a marketing perspective as Lead4Change.
