Benedict solutions tests positive with only reducing sugars and it will stay blue with non-reducing sugars. The positive test for Benedict's solution is the colour change to green, to yello and then to brick red with increasing concenteration. So the answer here would be A. Solution 2 is a non-reducing sugar and so do benedict's solution stays blue. Solution 1, 4, and 3 have increasing concentrations of reducing sugars and so the colour of benedicts solution darkens from green to brick-red, respectively.
