Which of the following would be an inappropriate activity for a DECA service project?

Creating a business to sell products is considered an inappropriate activity for a DECA service project because DECA's core mission focuses on enhancing students' understanding of marketing, finance, hospitality, and management through educational programs and community service initiatives. Service projects are designed to give back to the community and promote social responsibility, rather than to generate profit.

In contrast, the other activities mentioned align well with DECA's objectives, as they emphasize community involvement and support local initiatives. Hosting a charity run promotes health and encourages community participation, volunteering at a shelter addresses local needs directly, and organizing a school cleanup demonstrates a commitment to environmental stewardship. All of these options clearly reflect DECA's commitment to service and the development of leadership skills through community engagement.
