Hippies is a plural. A for me.

What is the OA?

[moonraker]

yeah i too would go with A for 2 obvious reasons.........

number 1 : Hippies is a plural form of Hippy.... so we need the word " their" and not its

this leaves us two options . ........... A and C

C has only difference - " that".......... now this is singular noun modifier but we have a plural subject......

So the correct answer is A
