Who rejected the idea that sociologists should study individual Psychology?

Correct option is C

Emile Durkheim

Emile Durkheim, a key figure in sociology, strongly rejected the idea that sociology should focus on individual psychology. Instead, he argued that sociology should focus on social facts, collective phenomena, and the structures of society. He believed that the study of individual behavior and psychology was the domain of psychology, not sociology. Durkheim's emphasis was on how society influences individual actions, rather than studying individuals as separate psychological units.
