Answer:

XYZ Company

Determining the pay rates of marketing professionals:

The statement that best describes the amount of variation when the R2 value turns out to be 0.85 is:

c. A large amount of the variation in market pay can be explained by company's job structure.

Explanation:

If the R2 were 1, then we can conclude that the whole variation in the market pay rates is explained by XYZ's job structure.  But with R2 less than 1 but greater than 0.5, we can only conclude that a large part of the variation in the market pay rates is explainable by XYZ's job structure.  And if the R2 is less than 0.5, we can confidently conclude that the variation in the market pay rates is not due to XYZ's job structure.
