According to USDA Regulations, how many members from one administrative unit can an IACUC have at maximum?

Under USDA Regulations, an Institutional Animal Care and Use Committee (IACUC) must maintain a diverse membership to ensure the committee's independence and objectivity. Specifically, the regulations stipulate that no more than three members can come from a single administrative unit within the institution. This rule is aimed at preventing any potential conflicts of interest or undue influence that could arise if too many members are affiliated with the same department or unit.

Thus, the selected option aligns with the established guidelines that promote a balanced and fair review process for animal care and use protocols, ensuring that diverse perspectives are represented in the committee's deliberations.
