Answer:

B. counterpunching.
C. maintaining a social boundary.
D. relieving an unpleasant situation.
C) maintaining a social boundary
Step-by-step explanation:
The police are meeting the citizens need of maintaining a social boundary.
Social boundaries can be defined as social rule relating to a society. Social boundary is the rule guiding the way of life of a community. It is a rule that is acceptable by a society as a way of life.
Social boundary makes it easier to determine where a person originates from because of their manner of behavior. Social boundary of one community differs from another community. It is safe to say that what is constantly as a crime or rude in a society might not be in another society.
For example, in Yoruba land(Nigeria) it is rude for a person to call an older person by his/her name while in Hausa land(Nigeria), it is a norm to call each other by name either young or old.
