According to a 1996 survey by the National Association of College and University Business Officers, more than three times as man
y independent institutions of higher education charge tuition and fees of under $8,000 a year than those that charge over $16,000. (A) than those that charge
(B) than are charging
(C) than to charge
(D) as charge
(E) as those charging
According to my research on correct English grammar, I can say that based on the information provided within the question the correct statement would be "than those that charge". The other statements are all grammatically incorrect and would not make sense if added to the statement in the question.
