Answer:

Option D, Phloem

Explanation:

Phloem and Xylem are parts of vascular system of a plant. While phloem transports food produced in the leaves, Xylem transports water absorbed by roots to all other parts of the plant. Phloem tissue is composed of cambium cells and sieve tubes which run all along through the plant body thereby allowing transmission of food to all non photosynthesizing parts of the plant such as stem, roots, etc . The transportation through phloem tissue is bi-directional unlike the transportation through xylem.
