Answer: A

While the semi-colon is not underlined, it's an important part of the sentence. The clause before the semi-colon is a complete sentence; the clause after it must be one, as well. As written, there are no problems of this nature with the sentence.

Another detail to note is the verb form "accounts." In the original sentence, it corresponds with the subject "completion," which is singular, so "accounts" is correct. The plural "account" appears in (C), (D), and (E), and in (C) and (E), it is supposed to correspond with a singular subject, so those two choices are incorrect.

(B) is wrong, and this is also because of subject-verb agreement. "The remainder" is singular, so it should be "the remainder...goes," not "go." (D) is also incorrect. The verb "to account" suggests that this will happen in the future, while there is no such hint in "goes" in the same sentence. The verbs don't agree. Choice (A) is correct.
