The correct answer is letter B

Ethnography studies and reveals the customs, beliefs and traditions of a society, which are passed on from generation to generation and which allow the continuity of a given culture or social system.

Ethnography is inherent in any aspect of Cultural Anthropology, which studies the processes of social interaction: the knowledge, ideas, techniques, skills, norms of behavior and habits acquired in the social life of a people.

Ethnography is also an integral part or discipline of ethnology, which deals with the descriptive, classificatory and comparative study of material culture, that is, of the artifacts found in different societies.

Ethnographic research has anthropological or ethnographic bases, it is based on observation and hypothesis survey, where the ethnologist seeks to describe what, in his view, that is, in his interpretation, is taking place in the researched context. One of the characteristics of Ethnography is the physical presence of the researcher and observation on the spot.
