Answer:
c a sharp fall in reserves and a rise in the domestic interest rate above the world interest rate.
Step-by-step explanation:
A devaluation of fixed foreign exchange rate of a country will make the local currency cheaper compared to other currencies.
This implies that other countries will benefit more from buying the countries goods which are now cheaper (exports).
Imports will be more expensive as foreign currencies will have higher value.
Inflation results in this situation leading to increased interest rates aimed at curbing the fall of price of goods.
In order to maintain a level of stability in the economy also the reserves of the country will be used to stabilise the local currency. So reserves will fall.
