A committee found that students having academic problems were doing too little studying and playing a lot of sports
-->
Director prohibits them from playing sports, saying this will ensure they do well academically
What's the problem here? We don't know if the sports are what's making them struggle in the classroom! It's a class correlation-causation issue. Maybe the sports are helping them, and it's the too little studying that's the problem (assumption #2: that it's the sports time that's causing the too-little studying).
So the director fails to establish that:
(A) is not quite on point. We're not worried about students who don't have academic problems.
(B) is too extreme. He doesn't need to establish that ALL students who do well don't participate in sports, just that these don't.
(C) Yes! He never establishing this link for these students.
(D) again, like (A), we're not worried about students who do well already.
(E) way out of scope.
As for your GREAT question:

YES! Exactly. The author fails to establish a necessary condition. If there is a sufficient answer choice that goes above and beyond what the argument needs, like (B) does here, then it's not a flaw that it wasn't established, right? It isn't necessary! Great job.
