ExplanationChoice A: No. The list of sources of
methane in the atmosphere is not parallel.
Choice B: No. This choice produces a sentence fragment lacking a main verb.
Choice C: Yes. This choice lists sources of
methane in the atmosphere that are parallel and produces a complete sentence with the predicate
is generated.
Choice D: No. The list of sources of
methane in the atmosphere is not parallel.
Choice E: No. This choice incorrectly combines the concepts of fossil fuel development and fossil fuel use into a single source of
methane in the atmosphere, thereby changing the intended meaning of the original sentence.
The correct answer is choice C.
