Correct Option: B

Devaluation refers to a decline in the value of a currency in relation to another, usually brought about by the actions of a central bank or monetary authority. Devaluation is sometimes used more generally to describe any significant drop in a currency’s international exchange rate, although usually a decline caused by market forces with no government intervention is termed a depreciation. Devaluations are most often associated with developing countries that don’t allow their currency prices to float freely on the open market.
