my school the answer is C ...
this answer was correct few months ago and now it has been adjusted to sth wrong
The correct order of water loss from the leaf is:
C. 2 → 1 → 3 → 4
Here's why:
Veins (2) – Water is transported to the leaf through the xylem in veins.
Mesophyll (1) – Water moves from the veins to the mesophyll cells, where it evaporates into the air spaces.
Substomatal cavity (3) – The water vapor collects in the substomatal air spaces.
Stomata (4) – Finally, water vapor exits the leaf through the stomata by diffusion.
So the pathway is: Veins → Mesophyll → Substomatal cavity → Stomata
