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

A.
as

B.
than

C.

[url=]D.

E.

Explanation:

this one isn't that bad if you get down to the "skeleton" of the sentence. to do that, you should kill intervening prepositional phrases that don't affect the grammar of the main sentence.
to this end, you can simply get rid of the following:
"per milligram"
"for another product"
"with the same active ingredient"
and you're left with:
a new drug is being sold for three times the price ____ the drug's maker charges.
once you see this, it should be more clear that (c) is the correct answer. if you're a non-native speaker and you can't recognize "that" as the word belonging in that blank, then here's the reason: it's because "price" is the direct object of "charges". when you turn around such constructions, you use "that":
i hit the ball --> the ball that i hit
she delivered the baby --> the baby that she delivered
etc.
