Answer:
C. seek a safe place and request law enforcement assistance.
Step-by-step explanation:
The most appropriate and logical action here is to seek a safe place and request assistance of any law enforcement agency. Law enforcement agencies are trained personnel to respond to crime and prevent it. In such a domestic violence situation, which is unexpected and was later recognized to have a gunman involved will have only a law enforcement agency to respond to it. Any attempt for an untrained man to apprehend the gunman may lead to injury or loss of lives.
Also, only a law enforcement agency is legally permitted to enforce the law to maintain public order and punish crime, requiring the members of a society to comply with the law.
