I feel like this is more of what friends you have but you could say hair color, height, eye color, etc.
The correct answer is B.
If you find yourself in a risky situation and you want to leave but are afraid of what the consequences the best thing you can do is hang around other people who support leaving. There is always strength in numbers, there is support and you can all leave at the same time to get out of the risky situation. That way no one can be singled out and be at risk.
