Why not D?
On negating D, we get that the average salary of the non degree requiring jobs will increase. This makes the argument fall apart...
Upon negating choice D actually strengthens the conclusion rather than weakening. If the average salaries of non degree requiring jobs increase too, then they would add to the total average salaries of all jobs in Karvonia. Hence choice D could not be an assumption.
Hope I made some sense.
