Solution
The correct option is B Apoplast In the apoplast pathway, the water molecule
moves across the cell wall and intercellular spaces without entering the
cytoplasm. The movement of water takes place from cell to cell by crossing the
plasma membrane of each cell. Thus, water passes at least two membranes for
each cell in the apoplast pathway.
