Detailed explanation-1: -Examples are glucose, fructose, glyceraldehydes, lactose, arabinose and maltose, except for sucrose.

Detailed explanation-2: -In above options, all are monosaccharides (reducing sugars) except sucrose.

Detailed explanation-3: -Answer: Sucrose is a non-reducing sugar since it does not dissolve in water.

Detailed explanation-4: -All monosaccharides are reducing sugars because they either have an aldehyde group (if they are aldoses) or can tautomerize in solution to form an aldehyde group (if they are ketoses). This includes common monosaccharides like galactose, glucose, glyceraldehyde, fructose, ribose, and xylose.

Detailed explanation-5: -Sucrose, glucose and fructose all are sugars. Glucose and fructose are monosaccharides and sucrose is a disaccharide of the two combined with a bond. Glucose and fructose have the same molecular formula (C6H12O6) but glucose has a six member ring and fructose has a five member ring structure.
