gwd13-8答案是C还是D呢

I would support D.

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

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

Here "that" modifies " milligram" therefore "that" is not correct.

为了方便分析，把插入成分per milligram去掉
句子变成
A new hair-growing drug is being sold for three times the price——the drug’s maker charges for another product with the same active ingredient.
在空格中应该填入什么呢
答案是that
that引导定语从句，修饰price，that在从句中做charges的宾语（charge的用法：charges ten dollars for a haircut）
为什么选that？
看以下例题
tom的年龄是jerry的3倍，
这样的句意通常可以有三种表示方法：
1 tom is twice older than jerry
2 tom is 3 times as old as jerry
3 tom is 3 times the age of jerry
可以看出，此题和第3种的表达方法类似，只不过把后置定语of jerry改成定语从句而已
此题最容易误选的of what
为什么错？
what = the thing that 在此题中=the price that
选of what则意味
3 times the price of the price that the drug's maker charges for
错误已经很明显了

我想追问一个问题，如果说再加一个选项", which", 那这个和", that ”哪个好？
