Step-by-step explanation:
Reason for a Central Bank to Sell Its Domestic Currency
The central bank might sell its domestic currency for several strategic financial reasons, but within the options provided, the correct answer is to help exporters in their home country sell goods overseas. When a central bank supplies more of its currency to the foreign exchange markets, this can lead to a depreciation of the domestic currency, making exports more competitively priced and thus more attractive to foreign buyers. It is not done for the purpose of speculating to make a profit or to discourage tourism, nor is it meant to lower the price of imports, as this would actually have the opposite effect.
It is important to understand that central banks operate to stabilize their country's economy, not to turn a profit like private investors. Measures that promote export growth can be helpful to the balance of payments and can support domestic employment and production industries. The central bank is also constrained by the amount of foreign currency reserves it holds, implying that there is a limit to how much it can intervene in the foreign exchange market.
