Detailed explanation-1: -The process of loss of water in the form of liquid drops from the edges of leaves or the tips of veins through hydathodes is known as guttation. This process usually happens in herbaceous plants when the humidity is and the root pressure is high and the rate of transpiration is low.

Detailed explanation-2: -Guttation usually occurs in the plants growing in the warm and humid climate. It usually occurs during night or in the morning when the absorption of water exceeds that of the transpiration. Due to which, root pressure is increased in xylem and water comes out through hydathodes.

Detailed explanation-3: -It occurs through specialized pores called hydathodes. It occurs in herbaceous plants when root pressure is low and transpiration is high. No worries!

Detailed explanation-4: -As this water contains different organic and inorganic substances from the plant it is considered impure. Also, guttation is of universal occurrence. Thus the correct answer is option C.
