  • C
    When the root pressure equals the rate of transpiration.
  • D
    When the root pressure as well as rate of transpiration is high.
✓

Answer

Correct option: A.
When the root pressure is high and the rate of transpiration is low.
The process of exudation of liquid drops from the edges of leaves is called guttation. Usually it occurs though special structures, called hydathodes. It is the process by which fully turgid plants remove extra water. The cause of guttation is mainly root pressure $($when the root pressure is high and rate of transpiration is low, guttation takes place$)$.
