if future spot rate is 1.0615 (predicted by PPP), the situation of us exporters does not change.
But because the future spot (0.9808) is lower than the predicted one (1.0615) the situation of us exporters worsened and therefore have competitive disadvantage (=they earn less USD).
If the predicted rate were 0.9153 and future rate 0.9808, the us exporters would have competitive advantage.
so you dont need to know the rates and dont need to calc anything just compare the predicted rate and reality.
thats why I think it is C
