The correct answer is: D. tries to be unfriendly by taking no notice of her.

A cold shoulder is a gesture of disapproval or rejection, typically conveyed by ignoring or turning away from someone. In this case, the man is trying to show Sarita that he does not want to be friends with her by ignoring her.

Option A is incorrect because pushing someone with your shoulder is a physical act of aggression, not a cold shoulder. Option B is incorrect because creating troubles for someone is also a form of aggression, not a cold shoulder. Option C is incorrect because insulting someone is a form of verbal aggression, not a cold shoulder. Option E is incorrect because arguing with someone is a form of conflict, not a cold shoulder.

In conclusion, the man is trying to be unfriendly by taking no notice of Sarita. This is a clear sign that he does not want to be friends with her.
