Answer: 2. C

Key idea: in dicot guard cells the wall facing the stomatal pore (inner wall) is thick and the outer wall is thin.

In the figure, A is a subsidiary/epidermal cell, B is the guard cell, C is the thickened inner wall next to the pore, and D is the pore. The unequal thickening lets the cells bend outward when turgid, opening the pore. The answer is C.
