The correct option is B

The cell wall is freely permeable and the cell membrane is semi-permeable.

$\begin{array}{ccc}& \text{Cell wall}& \text{Cell membrane}\\ 1.& \text{It is non-living}& \text{It is living}\\ 2.& \text{It is present outside the cell membrane}& \text{It is a thin outer membrane outside the cytoplasm before the cell wall}\\ 3.& \text{Mainly composed of cellulose}& \text{Mainly composed of lipids and proteins}\\ 4.& \text{It is freely permeable}& \text{It is semi permeable}\\ 5.& \text{Present only in plant cell}& \text{Present in both plant and animal cells}\end{array}$
