Correct Answer - Option 2 : Call the police and inform about the incident
Trying to take cover to save myself is irrelevant to the situation. Two persons are fighting and not attacking others. So, the point of covering and saving myself in such a situation is pointless.
Calling the police and informing them about the incident is the most preferred course of action. Two people are fighting and they may end up harming each other. It is better that the police looks upon the matter and puts an end to the fight.
Standing there and making a video, then uploading it to my friend is completely wrong. A fight may turn out to be dangerous and moreover fight is not something to enjoy or share with friends.
Trying to find out the problem and intervening won’t be of much help as two people who are fighting are less likely to listen to strangers and discuss the reason behind their fight.
Hence, ‘option 2’ is the correct answer.
