I think undergraduates. I´m going to second guess myself and say alumni. Wait, I talked it over with myself and I think I wrote the right answer first. Lol, hope this helps.
I imagine it would be A seeing as primary sources are usually the way to go. It could also be B, though. Which answer did you have in mind? If it was A or B, go with youŕe gut on this one! (I'm leaning more towards B)
