Devaluation is the term used to describe the reduction in the value of a country's currency in relation to other country's currencies. When a country devalues its currency, it reduces the exchange rate of its currency with respect to foreign currencies, making it cheaper to buy goods and services in the international market. Devaluation typically occurs when a country's government or central bank intentionally takes measures to lower the value of its currency, such as reducing interest rates or selling off foreign currency reserves. This can be done to make a country's exports more competitive by making them cheaper for foreign buyers, and to encourage domestic production by making imported goods more expensive. Therefore, the correct option is devaluation.
