Answer:
D. Those organizations that accept Public Health Service (PHS) or National Science Foundation (NSF) funding.
Step-by-step explanation:
Vertebrate animals are used in much scientific research due to the anatomical, chromosomal, or evolutionary similarity they have with humans. However, before the experimentation process, scientists must comply with ethical or political norms that prevent the conduct of non-ethical experiments or generate animal suffering.
The PHS, or Public Health Service, is a division of the department of health and human services whose function is to regulate public health in the United States.
All organizations that obtain money from PHS must comply with their policies when researching using vertebrate animals.
