A is incorrect because although many countries require deposit-taking banks to place a reserve balance with the national central bank, this is not always the case. C is incorrect because some central banks pay no interest on reserve funds, and sometimes even charge for keeping reserve funds. 问：如果按着机会成本-即 次优收益 来理解B?
