Answer: (B) the idea that responding to deviance promotes social unity.
Explanation:
According to Durkheim one of the functions of deviance is promoting social unity. A functioning society has a value consensus, common rules, and values that most people have acquired through socialization. That value consensus is strengthened through the policing of the boundaries, applying both formal and informal penalties or rewards to either recompense those who follow the rules or discipline those who go against them.
