(C) Guttation is the exudation of water droplets from the margins or tips of leaves through specialized structures called hydathodes.It occurs when the rate of water absorption by roots is high and the rate of transpiration is very low, typically during the night or early morning.This high water content in the plant creates a $Positive root pressure$, which forces the water out through the hydathodes.Therefore, $Positive root pressure$ is the primary cause of guttation.
