Facebook users between the ages of 18 and 29 report using facebook for what primary reason? ~~~ a- personal use b- academic use c- professional use d- none of the above

Hello again,
My A (Again)
Why: I would say A because teenagers in this age normally tend to use Facebook for fun. They tend to blog about their daily life, and unusefull things (Not trying to be disrespectful). They normally use it for fun and entertainment.
Why not B,C and D: Facebook can be used for acedemic use, but teenagers do not normally use it for that. They don't use it for professional use either? Not D because there is a reason that teens use facebook.
A
I hope I helped :) I apologize if it's wrong
