Which states adopted the national DECA constitution and official name in 1948?

The correct answer pertains to the historical context of DECA's formation. In 1948, DECA was officially established with a national constitution, and this included the involvement of 17 states that officially adopted this framework at the time. Kentucky and Louisiana were among those states, highlighting the organization's early reach and the foundational group that contributed to DECA's national structure. This is significant because it marks a pivotal moment in DECA's history, as it transitioned from local chapters to a unified national association.

The other choices list groups of states that did not collectively or entirely represent those that adopted the national constitution at that formative time in DECA's history. Understanding the specific states involved offers insight into the organization’s early growth and development across the country.
