You should open the wine about three hours before you use it.

Option A: "Wine should be opened about three hours before use." This is grammatically correct and a possible passive voice transformation.
Option B: "Wine should be opened by you three hours before use." While technically correct, adding "by you" is usually unnecessary in passive voice when the actor is obvious or unimportant. It also doesn't address the second part of the original sentence.
Option C: "Wine should be opened about three hours before you use it." This is incorrect because it's still using active voice ("you use it") in the second part of the sentence.
Option D: "Wine should be opened about three hours before it is used." This is also a good passive voice transformation. It addresses both part of the original sentence

Comparing Option A and Option D,Option D captures full meaning from the original sentence.
So,the correct answer is D.
