Sometimes characters feel out of place. Maybe they wear the wrong clothes to a party, or they don't fit in with a group of people. They are made to feel unwelcome.
This would be an example of:
a
character vs. nature
b
character vs. self
c
character vs. society
d
character vs. character
I believe so because the character (s) aren't facing each other, they just feel unwelcomed by groups of people because of what they where, which would indicate character vs society.
