Respuesta :
Empathy is the act of sharing and understanding the feelings of someone else. So I'd go with:
C. Ask him how he’s feeling
C. Ask him how he’s feeling
You should ask him C how he is feeling, B wouldn't work because he would know that you saw how he is feeling and make him even more upset. A would make him angry as you don't even know why he is upset. and D would make him think you don't even care.
