Q.Which among the following is correct?

All four statements about the apoplast, symplast, and transmembrane pathways of water movement are individually correct, so the right combination includes all of them.

Water moving from the soil into the root xylem can take three routes:

1. Apoplast pathway: water moves through the cell walls and the intercellular spaces (which are non-living, water-permeable material) without ever crossing a cell membrane, until it reaches the Casparian strip. Because it isn't slowed by having to cross membranes, this route offers the least resistance and IS the fastest pathway. This matches statement (i).
2. Symplast pathway: water moves through the living cytoplasm of one cell to the next through plasmodesmata (fine cytoplasmic channels connecting adjacent cells), so it interconnects neighbouring cells — matching statement (iii).
3. Transmembrane pathway: water repeatedly crosses cell membranes as it enters one cell and exits into the next; when a cell has a large central vacuole, the water also crosses the tonoplast (the vacuole's membrane) as part of this route — matching statement (ii). …
