Answer: D) Social norms
Explanation: Social norms are general social norms, meaning accepted by society as unwritten rules, and these rules relate to what behaviour is acceptable, that is, norms about how to behave. Such norms define rules, for example for certain social groups, classes, boys, girls, etc., but also at a higher cultural level, for example, some norms differ from culture to culture. In each case, social norms provide a specific model or idea of how to behave within certain groups, cultures, etc.
