Answer: Option C

Translocation of carbohydrates mostly takes place in the form of Sucrose.
In plants, sucrose is the major transport form for photo-assimilated carbon and is both a source of carbon skeletons and energy for plant organs unable to perform photosynthesis.
As a molecule translocated over distance, sucrose has to pass through several membranes. It is transported around the plant in phloem vessels.
