I think "what" here can not be replaced by "the thing that" because in the sub clause there is an accusative "another product". BTW, I support C "that"

，that...非限定性的从句，这样使用that不对啊。支持选D

我也是把what 理解为 the price that

想了半天，还是觉得that比较合理。表明 a price the drug's maker charge for another product.

另外，of what用在此处是不太好，如果一定要用what在这个句子里面，感觉这样会更好些。

A new hair-growing drug is being sold for three times what the drug’s maker charges for another product with the same active ingredient.

不知道为什么，就是觉得of what读着爽。难道我也有语感了？

c不对 整理是charge the price for doing sth 应该是charge for doing sth /sth at teh price

偶也觉得应该是D， of what=of the price that

唉，只是看讨论看的偶越来越糊涂了

我也选D，但是看了讨论越来越糊涂了。

catcenter

讨论看了半小时,,,,

暂且就跟着大部分NN走选D吧...

按照XDF老师讲的首先就要排除C啊，他们的说法是THAT不可以修饰非限制性定从，前面是不可以有介词和逗号的啊。我个人认为选E。
