Solution

The correct option is B
Prevent damages to stem and root

To prevent compression and bending in stem

Xylem cells have extra reinforcement in their cell walls, and this helps to support the weight of the plant.

The transport systems are arranged differently in root and stem – in the root it has to resist forces that could pull the plant out of the ground. In the stem it has to resist compression and bending forces caused by the weight of the plant and the wind.
