Solution
The correct option is B Root pressure
Guttation or exudation of xylem sap, is the loss of water in liquid state. It occurs through hydathodes. The force responsible for this process is root pressure. Guttation is easily observed in conditions of high humidity, when soil is well watered. In such conditions transpiration loss of water is less and extra water absorbed by roots oozes out through hydathodes in liquid state.
