D.
It is comprised of maltose and fructose
Sucrose is a disaccharide, mainly composed of fructose and glucose. It is a non-reducing sugar because it does not have a free aldehyde or ketone group. During the transportation of sucrose from source to sink through phloem it gets accumulated in the cytoplasm of the cell, after getting hydrolysed into glucose and fructose.
