Although biologists have made tremendous progress in mapping the human genome, the genetic roots of most common diseases remained largely elusive.

(A) remained

(B) had remained

(D) are remaining

(E) remains

正确答案：C

解析：Choice (C) is correct. It avoids the verb tense error of the original. The past tense verb “remained” is not consistent with the present perfect tense verb “have made” and should be changed to the present tense verb “remain.”
