Covington College has four full-time Classics professors, but only 12 Classics majors. This three-to-one student-to-professor ratio is the lowest in the college. Since the college is facing financial difficulties, and since the tuition fees from just 12 students is not sufficient to pay the salaries of 4 full-time professors, the college should cancel the Classics program to reduce expenses.
Which of the following, if true, most weakens the conclusion above ？（）
A. Professors in the Classics department teach popular language and literature classes that are attended by hundreds of students who are not Classics majors.
B. Students at Covington College pay, on average, $22,500 per year in tuition and fees, while the average professor of humanities receives a salary of $61,500 per year.
C. A well-regarded Classics program adds prestige to a college or university.
D. The Classics department has already decreased in size from six frill-time professors 10 years ago.
E. The study of classical literature and languages is increasingly irrelevant to the high-tech workplace of today.
