Solution
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. Glycogen and cellulose are polysaccharides and are also non reducing in nature.
Galactose, maltose and lactose are reducing sugars. Galactose is a reducing sugar as it has a free ketone group
