Answer

Correct option: C.
Cold and humid
The exudation of xylem sap at the edges or tips of the leaves of some vascular plants, like grasses is called guttation.
Unlike transpiration, it takes place only in certain conditions like cool and highly humid atmosphere.
It is because plants can absorb up a limited amount of water.
The excess water is secreted from the roots through the xylem and out through the hydathodes or water glands.
