Which of the following are national elected officers of the FBLA High School Division?

The correct answer includes the National President, Regional Vice Presidents, National Secretary, and National Treasurer, which reflects the official structure of the FBLA High School Division. These positions are recognized in the organization's bylaws as elected national officers responsible for leading and representing the organization at various levels.

The National President is the highest-ranking officer, providing overall leadership and direction. The National Secretary and National Treasurer have specific responsibilities related to record-keeping and financial management, respectively, and they are vital to the functioning of the organization. Regional Vice Presidents are essential as they represent specific geographic areas, helping to ensure that all regions are represented in national decision-making.

The other choices include positions that are not part of the national elected officer structure as defined in the bylaws, such as Regional Directors and State Presidents, which, while important, do not fall under the national level. Thus, choice B correctly identifies the roles that are officially recognized as national elected officers within the FBLA High School Division.
