Solution

The correct option is B

Transpiration


In trees, water is lost from the leaves due to a process known as transpiration. Transpiration, when it occurs, creates a suctional force that pulls water in the soil along with dissolved minerals from the roots and all the way to the leaves. This transport of water occurs through xylem.
Root pressure can help transport water to short heights only.
