Solution
The correct option is D Reducing sugar
Reducing sugars are those that can reduce ions due to the presence of free aldehyde and ketone groups. Benedict's reagent consists of sodium carbonate, sodium citrate, and copper(II) sulfate pentahydrate. On heating the reducing sugar in the presence of alkaline Benedict's reagent it forms enediols which further reduces copper ions to form copper oxide which appears as a brick red precipitate. The color changes from blue to brick red confirms the presence of reducing sugar.So, the correct answer is option D.
