Solution
The correct option is A Guttation
The process of exudation of liquid drops from the edges of leaves is called guttation. Usually
it occurs through stomata-like pores called hydathodes. It is this
process by which fully turgid plant 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). Hydathodes are
stomata-like pores, generally present at the tips or margins of leaves
of those plants that grow in moist shady places(e.g., Tropaeolum). So, the correct answer is 'Guttation'.
