Concept:The police maintain order and enforce the law, but they do not carry out judicial punishments.
Explanation:The functions of the police include enforcing law and order, protecting life and property, and arresting suspects.
Prosecuting law breakers is part of police work through the legal process.
However, public execution of law breakers is a judicial or penal function, not a normal duty of the police.
Executions are carried out by authorized prison or execution officials after a court sentence, not by the police.
Therefore, among the listed options, public execution is not a police function.
Answer:Option A — Public execution of law breakers.
