What makes a person feel marginalized?
A. Making friends easily
B. Feeling that one is an outsider
C. Being invited by others to join them
D. Feeling popular with others
B is the correct answer. Being 'marginalized' means that you feel as if you were an outsider, on the margin, alone and different. It means that you feel rejected by the rest of your peers, so quite the opposite from A, C, and D.
