Which of the following is NOT considered a permissible purpose for using animals in research?

The use of animals in research is guided by a set of ethical standards and regulations that define permissible purposes. Basic research, forensic inquiries, and the development of medical drugs all fall within accepted guidelines for the use of animals because they contribute to scientific knowledge, public safety, and advancements in medical treatments.

Basic research is crucial for understanding biological processes, which can lead to significant discoveries. Forensic inquiries may use animals in various ways to help solve crimes or understand ecological impacts, thereby benefiting society. The development of medical drugs is another prominent area where animal testing is deemed necessary for safety and efficacy before trials in humans.

In contrast, using animals for entertainment purposes does not align with these ethical frameworks. It is often criticized for prioritizing human amusement over animal welfare, lacking the scientific objective or necessity present in the other categories. Thus, utilizing animals for entertainment does not meet the criteria for permissible research purposes.
