I would opt for C: if the option of vacating the scene was reasonably available. If escape were not an option then B: would be the better choice. In a chaotic, evolving scene you cannot be sure someone is targeting you or your loved ones as clearly as if you were being attacked on the street or in your home. Remember, in this chaotic scene you will be just another person holding a gun to the police and they will not know if you are a good gal/guy or not.
