Solution
The correct option is C Root pressure
Guttation is the loss of water in the form of liquid through hydathodes. The most important force responsible for guttation is root pressure, which develops in conditions of high humidity, because when roots absorb mineral salts water follows passively but transpiration loss of water is less. This develops positive root pressure.
