Answer:
D. Increase; increase
Step-by-step explanation:
Exchange rate is defined as the amount of one currency that can be exchanged for another currency at a particular time.
Demand and supply affects exchange rates of currencies.
Currencies that are in more demand tend to have higher exchange rates, while those with low demand will have low exchange rate.
In this instance an increase in preference for US goods will cause an increased demand for dollars. The dollar becomes stronger against the Peso.
It will take more pesos to purchase the dollar, so equillibrum exchange rate of peso to dollar will increase.
