Solution

The correct option is A Plasma membrane
A constant osmotic pressure can be maintained by the control of salt and water concentrations.
These concentrations can be maintained by free flow of solutes across a permeable membrane.
Plasma membrane is permeable while stratified epithelial membrane is impermeable to solutes.
So, the correct answer is 'Plasma membrane'.
