It's pretty logical once you know what to look for (Economist GMAT Tutor taught me this):

When you use "Which" it becomes some sort of an indirect clause (I may have the wording wrong) that essentially means that when you use "Which" it is often additional information whereas "That" provides necessary information.
In this case, the information is necessary to make sense of what is being said after the last comma. Rule out options C, D, E.
Between A and B, B implies that the student had been suspended once before as well, so that is ruled out. A!! :)

A-ok
B-is incorrect because once incorrectly refers to resulted suggesting that the student can be expelled a number of times, which is nonsensical
C-"which" incorrectly refers to classroom
D-GMAT generally doesn't prefer "being" and expulsion is far better than "being expelled"
E-"teachers are apt to refer " is awkward
