Hello smile22,
This is a typical "false dilemma" question. Answer (E), "fails to consider that some students may be neither fascinated by nor completely indifferent to the subject being taught", shows the problem, i.e., that two extremes are being considered (obsession with subject vs. total boredom with subject), ignoring the vast middle reaches of students who may be *moderately* interested in a subject.
Answer (C), "fails to consider that the incentive of grades may serve some useful nonacademic purpose", is pretty much out of scope since we're talking about academic stuff, not nonacademic.
Hope this helps,
David
