Answer:
D) In the short term, unemployment rates would depend on other market factors.
Step-by-step explanation:
In the short term the raising of the retirement age would not affect the unemployment rates, this is because the short term, 3 months, would not reflect most of the jobs that are being freed by the retiring workers, in the long run, lets say, 3 years it will be perceivable in the unemployment rate because the people entering the workforce will not have does jobs or the subsequent job that someone retiring releases.
