Answer:
Option B - Under a fixed exchange rate system, if a central bank conducts a monetary policy, then it puts pressure on the exchange rate and the central bank would have to offset that effect.
Step-by-step explanation:
Central banks are required to initiate measures to keep the exchange rate fixed, such that any move by them which causes movement of exchange rate will have to be countered by themselves.
Hence, if a central bank administers a monetary policy under a fixed exchange rate system, it would exert pressure on the exchange rate and the central bank would have to counteract that effect.
Therefore, option B is the correct answer choice.
