Dear student,
The correct answer is (a).
The cell wall is the outermost covering of the plant cell which protects the cell from infection and prevents the entry of harmful microorganism to enter the cell.

It is permeable structure and not selectively permeable.Hence, it allows small molecules and other substances to easily pass through it.

It is the plasmodesmata or plant cement which help in a cell to cell interaction and not the cell wall of the plant cell.
