I guess I got this question the roughest because for me: A has 2 sub-options; B has 3 sub-options; Definitely not C (It reminds me of bad times with someone that may have a few "mental differences", which is the same guy who ate a plastic water bottle twice within the same month [for fun]!); D is basically a quarter of my school, so that's a big no!
I guess that I'll have to choose B-b because she's the least annoying and we go to different schools, so I don't have to work with her 'til I get home.
Sorry if it's a bit long, but that's all I could do...
