Which of the following is NOT one of the four regions of national DECA?

The correct answer is based on the organizational structure of national DECA, which divides its members into specific regions. The four recognized regions are the North Atlantic, Central, Western, and Southern, rather than an Eastern region. This means that the Eastern designation does not exist within the current regional framework of DECA, making it the correct choice for the question. Each of the other regions mentioned in the options serves as proper classifications within the DECA organization, exhibiting how members collaborate and network within these specific areas. Understanding this regional classification is essential for members as it helps in organizing competitions, events, and leadership opportunities tailored to their geographic locations.
