Correct Answer: Option A

Explanation

Xylem plays an essential 'supporting' role providing strength to tissues and organs, to maintain plant architecture and resistance to bending.

While the primary role of Xylem is to transport water and dissolved mineral salts upward from the roots, it serves a dual purpose. Mature xylem vessels and tracheids contain thick cell walls heavily reinforced with lignin. This structural compound provides immense mechanical strength and rigidity, directly supporting and strengthening the plant stem to keep it upright.
