Detailed explanation-1: -The correct option is A Galactose. Carbohydrates that have a free aldehyde or keto group, are called reducing sugars. Whereas if there is no free aldehyde or keto group then the carbohydrate is called a non-reducing sugar. Sucrose is an example of non-reducing disaccharide.
Detailed explanation-2: -Sugars that contain aldehyde groups that are oxidised to carboxylic acids are classified as reducing sugars.
Detailed explanation-3: -Those sugars which act as reducing agents are called reducing sugars. They contain an aldehyde (-CHO) are or a ketonic C = O all monosccharides and disaccharides (except sucrose) are reducing sugars, e.g., glucose, fructose, lactose etc.
Detailed explanation-4: -Sucrose is a non-reducing sugar.
