Answer:
The best answer to the question: Which of the following scenarios is an example of normative influence on behavior?, would be, A: Nobody at Emily´s new office wore sandals or denim, so she decided not to either.
Step-by-step explanation:
Normative influence, also known as Normative Social Influence is a form of social influence in which the acts, and behaviors of a group influences the way that an individual will also behave. The reason to do this is that the person, being a social entity, wishes to fit into the group, be accepted, and in order to accomplish this, she/he must meet the criteria and standards acceptable to the group, even if the person does not internally accepts them. In this case, Emily is at a new job and of course she must wish to adapt to the environment, so, even if she doesn´t know if it is allowed or not, Emily allows her own wardrobe choices to be dictated by what she sees around her, which is, her coworkers do not wear sandals or denim. So she won´t do that either, even if there is no explicit rule prohibit the use of such apparel.
