Answer: specific deterrence
Step-by-step explanation:
What is specific deterrence ?
Specific deterrence refers to the punishment given to someone who has committed a particular offence in order to ensure that they don't commit it again in the future.
The purpose of this policy is to discourage the person from thinking about committing an act against the law again.
It ranges from fines to spending a particular sentence in jail.

He is now determined to never break the law again because he doesn't want to receive the punishment again which will put him the same terrible experience all over again.
Specific deterrence has taken its effect on him.
