Explanation

Creating a filter: we flow through the original sentence and may not see an error. We can move on to choice (B).

Finding objective defects: in (B), the phrase "decreasing and increasing with altitude" seems to be a distortion of the intended meaning. So (B) is probably out. (C) looks better. The subject of the main clause is near its verb, in that "troposphere" is separated by only one modifying phrase from "gives way." Also, in (C), it's easier for us to understand that all the stuff at the front of the sentence is to define the tropopause in terms of the troposphere and the stratosphere. By contrast, it's unclear in (A) what "in the tropopause" is modifying. Is it simply where jet streams reside? Therefore, (A) is out and (C) is in. Choice (D) distorts the intended meaning: "increasing temperature with altitude" is not supposed to refer to the jet streams, but rather to the stratosphere. Out. Choice (E) manages to combine the errors we just mentioned of (D) and of (A). So it's out and we are left only with (C). In this case, the answer choices were mostly jumbles of each other, and when that's the case, what's right and wrong will tend to depend on whether each sentence conveys the intended meaning correctly and clearly. The correct answer is (C).
