Solution
The correct option is B selectively permeable
The plasma membrane is selectively permeable in nature as it allows the passage of only certain molecules in and out of the cells. Not all the molecules are free to diffuse. On the contrary, the cell wall is freely permeable to molecules within the size of 30-60 kDa.
