Actually, it's A. No commas are needed in A.
In D, it should be like this - Juice, which can be made from fruits or vegetables, often contains added sugar.                                                                                 ^
Notice that D in the options doesn't have a comma after "vegetables", but there should be one there like I added above. 
Therefore, A is correct. Hope this helps!
