(A) has steadily increased, while the number of other students who enter the field has fallen - enrollments is plural
(B) has steadily increased, while other students entering the field have declined in number. - same as above
(C) increased steadily, while there was a decline in the number of other students entering the field - no verb plus wordy
(D) have steadily increased, while the number of other students entering the field has fallen - makes perfect sense with use of have and past tense fallen
(E) have steadily increased, while that of other students who enter the field fell- wrong
