Which of the following categories is NOT listed among common animals used in biomedical research?

• A. Dogs
• B. Cats
• C. Rabbits
• D. Primates

Answer: (C)

When evaluating which animal categories are typically highlighted as common in biomedical research, the emphasis is on species repeatedly named in standard references, training materials, and regulatory discussions. In many of these sources, dogs, cats, and nonhuman primates are explicitly listed as common categories of animals used in research. Rabbits, although widely used in specific areas (such as antibody production, ocular studies, and wound healing), are not always included in those concise lists. That discrepancy is why rabbits would be the category not listed in that particular context. The takeaway is that rabbits are indeed used in research, but they may not be emphasized in some standard lists alongside dogs, cats, and primates.
