GMAT Critical Reasoning (CR) | Re: Despite radical fluctuations during the previous decade, unit labor

Now, I fully understand why C is the answer. Well, I should first understand what "fluctuation" and "Stability" mean; these 2 words imply that the quantity of goods produced will either change or be unchanged.

The second way to look at this question is to eliminate all wrong answers, and hence C is left. The correct answer should be C
