Which statements about reducing sugars are true? d‑glucose (an aldose) is a reducing sugar. the oxidation of a reducing sugar forms a carboxylic acid sugar. a disaccharide with its anomeric carbons joined by the glycosidic linkage cannot be a reducing sugar. reducing sugars contain ketone groups instead of aldehyde groups. a reducing sugar will not react with the cu2+ in benedict's reagent.

The true statements are given below.

Explanation:

1 D glucose is a reducing sugar

2 The oxidation of reducing sugar forms a carboxylic acid sugar.

D glucose is a reducing sugar because glucose contain a free hydroxyl group (-OH)in its anomeric carbon.

 The oxidation of reducing sugar result in the conversion of -CHO group in case of aldose sugar and -CH2OH group in case of ketose sugar into carboxylic acid(-COOH).

there are no statements provided but here is why:

sulfur belongs to group 16 because it can be found in nature whether it is in a free or combined state.
