问题如下：
Which of the following statement best describes the money demand that hold the money to buy the assets which value will decline .
选项：
A. speculative demand for money.
B. Precautionary money balances.
C. Transactions money balance.
解释：
A is correct.
The speculative demand for money refers the demand that hold money and wait for potential opportunities (assets value will decline).
考点：speculative demand for money.
解析：题目中的表述是指货币的投资需求。这是想要在未来资产价格在下跌时候购买该类资产，所以对当前货币的持有需求。
想问下题目里的asset是只指债券嘛？还是代指其他所有可以用来做投机的资产，如房地产，股票之类的
