Which group is excluded from being a voting member of the DECA Inc. Board?

The correct choice identifies the two ex-officio members as the group excluded from being voting members of the DECA Inc. Board. Ex-officio members typically have a role that allows them to participate in meetings and discussions, but they do not possess voting rights. This structure is often designed to ensure that certain individuals, such as chairs or executive directors, can provide input and expertise without being part of the decision-making process, allowing the board to operate independently while still utilizing their knowledge.

The other individuals mentioned, such as the chair of the National Advisory Board and the Executive Director of DECA Inc., typically hold positions that do grant them voting rights and active participation in board decisions. Therefore, their involvement on the board is essential for the governance structure, unlike the ex-officio members who are intended to serve in a more advisory capacity.
