OA = C assumes that the "higher average salary" is not based on a "scarcity" or a limited supply of "people with college degrees".

Since the conclusion states that more workers will have college degrees, and that the increase supply of workers with college degree will also increase "average salary", and for this to happen, the increase of supply of workers should not have an affect on the average salary, such as a salary decrease.
