Solution

The correct option is B Polar
The translocation of synthesized food is always from the source to sink. The source is a region at which sugar is present in high concentration, whereas sink is the region of sugar utilization and hence, has a low concentration of sugar. Since translocation always occurs from source to sink, it is directional and polar.
Thus, the correct answer is option B.
