The non-reducing sugar sucrose is most commonly translocated in the phloem rather than reducing sugar. Why?

a.) because they are less reactive than their reducing counterparts

b.) because sucrose contains more energy than a monosaccharides

c.) because the ketone or aldehyde group is reduced to an alcohol or combined with a similar group on another sugar so as not to be oxidized 

Which one of the following statements is true about translocation of non-reducing sugar?
