The correct options are
A Make new laws and implement them within the monarchy
B Punish offenders and people who do not follow his/her orders within the monarchy
D Go to war over whatever reason at whatever time.
A monarch can make laws and implement them. If people did not agree with them or did not follow their orders, they could punish them. No one could question their orders or disobey them. But they are only powerful inside their own territory.
