What happens to exports when a currency appreciates?

When a currency appreciates, it essentially strengthens in value relative to other currencies. This appreciation makes goods priced in that currency more expensive for foreign buyers. As a result, exports typically become less competitive in international markets because foreign buyers can purchase imported goods at a lower cost if their currency remains stable or depreciates compared to the appreciating currency.

This leads to a decrease in demand for those exports, as higher costs deter foreign consumers from purchasing. In summary, the relationship between currency appreciation and export levels is characterized by decreased demand due to higher prices for foreign buyers, explaining why the correct answer is that they generally decrease due to higher costs.
