The correct answer is D. A study hall
Explanation:
In sociology, a normative organization or voluntary organization refers to a group of people that organizes for a common purpose but are not forced to do it which implies people gather voluntarily usually because they enjoy it or find this rewarding. This is the case of different clubs such as book club, movie clubs, among others, also applies to protest groups or similar groups. However, a study hall is not an example of a normative organization, because in study halls students are assigned to study if they do not have class and this is not voluntary or only joined by those that want to study but all students have in this room and they are even monitored.
