Final answer:
The correct term is C. the biomedical model of health which is rooted in Western scientific knowledge and practices for treating diseases.
Step-by-step explanation:
The term that refers to the set of principles underpinning Western medical systems and that defines diseases objectively according to the presence of recognized symptoms, with the belief that a healthy body can be restored through scientifically based medical treatment, is C. the biomedical model of health. This model draws significantly from biology and biochemistry and relies on scientific experimentation and clinical trials. Despite its aim for objectivity, biomedicine is influenced by Western cultural values and has been critiqued for its systemic prejudices, such as racism, classism, and sexism, which impact its effectiveness. Moreover, the effectiveness of biomedicine can be influenced by patients' trust and belief in scientific knowledge and the system itself.
