The correct match is "Sucrose - Non reducing sugar".

Here's why:

1. Cellulose - It is a complex carbohydrate or a polysaccharide. It is not a reducing polymer. It is found in the cell walls of green plants and it is not directly involved in reducing reactions.

2. Lactose - It is a reducing sugar. It has a free aldehyde group that can reduce copper(II) ions to copper(I) ions during the Benedict's test.

3. Sucrose - It is a non-reducing sugar. It does not have a free aldehyde or ketone group and therefore, it cannot reduce copper(II) ions to copper(I) ions during the Benedict's test.

4. Ribose - It is a reducing sugar. It is a monosaccharide with an aldehyde functional group, which allows it to act as a reducing agent.
