Solution

The correct option is A Uninjured edges of leaves near vein endings
Guttation is the loss of water in the form of liquid from the uninjured margins of the leaves is called guttation. The pores are known as hydathodes. The level of soil moisture is high which creates greater root pressure. This root pressure creates a force which allows exudation of water from the tips. It is favored when the transpiration is suppressed and the relative humidity is high
Thus the correct answer is option (A).
