我觉得是个定语从句price that maker charges

price of what maker charges 你要怎么理解呢 what makers charges 是个价格?但是,据我所知price of 后面都是标价物 the price of apple 而不是跟价格

the price，（ ），that the drug’s maker charges

that引导定语从句，先行词the price做定语从句中charge的宾语。

这里注意charge的用法，你就不会选 of what了。charge是及物动词，在这里的用法是charge...for ..

选D也有理由啊

3 times of sth，what 是maker charge的price，引导名词性从句

所以是A is being sold for 3 times the price of ...

这样有错么？
