While one requires oxygen and one does blank and anaerobic respiration are both forms of cellular respiration—that is, they are processes by which cells break down glucose to use as energy.
Which choice completes the text so that it conforms to the conventions of Standard English?
Explanation
Choice C is the best answer. A comma is the appropriate way to link the dependent clause “While...not” and the independent clause that follows.
Choice A is incorrect. This choice creates a run-on sentence error. “While...not” is a dependent clause, which must be separated from the independent clause that follows with some sort of punctuation. Choice B is incorrect. This choice creates a sentence fragment. “While one requires oxygen and one does not” isn’t an independent clause, so it can’t stand alone as a complete sentence. Choice D is incorrect. This choice creates a punctuation error. “While one requires oxygen and one does not” isn’t an independent clause, so it can’t be linked to the clause that follows with a semicolon.
