Which of the following is NOT one of the four divisions of FBLA?

The answer is D, FBLA Adult Division, because it does not represent one of the official divisions of the Future Business Leaders of America (FBLA) organization. The main divisions of FBLA include FBLA Middle Level, which caters to middle school students; FBLA, which is the main organization for high school students; and PBL (Phi Beta Lambda), aimed at post-secondary students.

FBLA does include divisions specifically tailored for younger students and those continuing their education beyond high school, but there is no division dedicated to adults as part of the standard framework. Hence, while there might be adult resources or involvement in the organization, the official structure does not classify a specific division for adults. This distinction clarifies why the Adult Division does not fit within the established organizational framework of FBLA.
