因为A是不可数的,改为deposit

deposits(当沉积物时时可数的)不能改单数那就跟后面的are冲突了和c consist
我觉得选项看着都没错
我只想问the deposits前的but是怎么回事，不可能出现吧。是不是你的题抄错了

首先我觉得句中的" although...but..."用法是错误的。

其次，我认为这道题备选项中B是错误的。因为在此题中，" rich"的意思“丰富；多”的意思，而" rich in"的意思是" producing or having a largest supply of sth"，这样看来" rich" 在此处属于绝对（极限）形容词。我们知道，绝对形容词是没有最高级形式的，因此句中的" rich"最高级形式是错误的。故此题选B.

最后，至于大家讨论的" deposits"一词，在此并无错误，它的意思是“沉积物”，可以作为可数名词。C、D两选项亦无错误。

although,but肯定不可。
可能LZ超错了
deposit没法改，后面有个are限制。
B错？只能这样吧，排除
