Which of the following components is part of DECA's membership?

The correct choice identifies alumni as a component of DECA's membership. Alumni play a vital role in the organization by providing a link between current members and the professional world. Their experiences and insights can contribute significantly to the DECA community, offering mentorship and networking opportunities for active members. This connection fosters continued engagement with DECA beyond high school, creating a support system for former students as they advance in their careers.

In contrast, while industry professionals can be involved in DECA as mentors or partners, they are not categorized as members. Elementary school students are typically not a part of DECA, as the organization primarily focuses on high school and collegiate levels. High school students are indeed core members, but they are only one segment of a broader community that includes alumni.
