Answer:
C (not positive about this)
Explanation:
Let's go through all of these answers first.
A- Structural, which means something that is part of the building part of this. I do not think that is correct, as it isn't very relevant.
B- Seasonal. While we don't have concrete evidence that's incorrect, let's keep going and see if something fits better than that.
C- Cyclial, which means to be part of a cycle. In this case, it'd be the cycle of unemployment. Which sounds pretty appropriate.
D. Frictional. This also is not relevant to the topic.
So we can cross out A and D and we are left with B and C. We can tell that C seems to be more appropriate for this scenario, so we are left with C as our answer. I haven't done much in this topic though, so of course I could be incorrect.
