Answer:a. provide a way of measuring our actions and punish us when our actions break the law
Explanation:People need to know what is the limit to what one can do or not do so that order can be maintained.
Without those set limit on what one can do or not do in the society or in another person, the world will be a chaotic place because naturally some of us have uncontrollable behaviours that need to be monitored or if not monitored one need to receive punishment for them to know that such behaviour is not acceptable .
The law helps regulate our behaviour and punish our unlawful actions which is crucial to protect those who can not protect themselves such as children.
