Solution
Option 1 -> In a BOP deficit, payments exceed receipts, so reserves are used up, not increased.
Option 2 -> When BOP is in deficit, the central bank must use official reserves to finance the deficit, causing reserves to fall.
Option 3 -> Official reserves are directly used to settle BOP deficits, so they are affected.
Option 4 -> A BOP deficit means the country needs financing, not that it's lending to others.
Hence, Option 2: Official reserves will fall -> In a Balance of Payments deficit situation, the country's foreign exchange outflows exceed inflows. To bridge this gap and maintain external balance, the central bank must draw down its official foreign exchange reserves. These reserves (including foreign currencies, gold, and SDRs) are used to finance the deficit by making payments for imports, debt servicing, or capital outflows. As these reserves are depleted to cover the shortfall, they naturally decrease. This is the standard mechanism through which BOP deficits are temporarily financed until corrective measures restore balance -> correct
