Final answer:
The correct option is d). Physiology focuses on the function of living organisms, which makes it crucial for understanding health and disease in animals, but it is not central to understanding the social context of human disease.
Step-by-step explanation:
The discipline of physiology is primarily concerned with the function of living organisms and their parts. It encompasses the study of how animals work and the fundamental biology of all animals, making it central to understanding both the health and disease of nonhuman animals. However, the statement that physiology is key for understanding the social context of human disease is false, as this is typically the domain of social sciences and public health disciplines, rather than physiology.
