Solution

The correct option is C Decrease, Increase
The permeability of plasma membrane increase with small sized ions and decrease with large sized ions because small sized molecules can easily diffuse across the plasma membrane.
Since, divalent molecules are smaller than monovalent molecules, hence, the permeability of plasma membrane increase with divalent cations like calcium and decrease with monovalent ions like sodium and potassium..
So, the correct answer is 'Decrease, Increase'.
