I would go with D. (Laboratory Animals) because the Lab Animals were most of the time treated in an inhumane way.

The Animal Welfare Act is a group of federal laws designed to ensure that laboratory animals receive the best possible care. A laboratory animal is an animal kept in a research facility, zoo, or educational institution. The laws also apply to breeders who supply animals for research or education. The laws set standards for the care of all warm-blooded animals except rats and mice. These standards address all aspects of an animal’s daily care and environmental conditions. The Animal Welfare Act specifies that a laboratory animal’s environment must be kept clean, at a comfortable temperature and humidity level, and free of sharp objects that could injure the animal. Specific requirements govern exercise for some species of animals as well as regular, consistent contact with other animals and humans. Laboratory animal technicians and their assistants are often responsible for ensuring that the facility complies with all regulations.
