Answer:
The answer is C. Cultural relativism.
Explanation:
Cultural relativism refers to the idea that beliefs, values, as well as practices related to a person, must be considered according to that person's own culture, instead of judging those elements against the criteria of another one.
Cultural relativism was established by Franz Boas concerning anthropological research in the early 20th century. After Franz Boas' death in 1942, the term became an important element among anthropologists to establish their synthesis related to some ideas developed by Boas.
