Answer:
D. lower demand for U.S. products and layoffs of U.S. workers
Step-by-step explanation:
"Currency appreciation is an increase in the value of one currency in relation to another currency. Currencies appreciate against each other for a variety of reasons, including government policy, interest rates, trade balances and business cycles.
[...] If the U.S. dollar appreciates, foreigners will find American goods more expensive because they have to spend more for those goods in USD. That means that with the higher price, the number of U.S. goods being exported will likely drop. This eventually leads to a reduction in gross domestic product (GDP), which is definitely not a benefit."
