Solution

The correct option is D (ii), (iv) & (v)
(ii) In case of plant cells, osmosis is unidirectional in XYLEM and bidirectional in PHLOEM transfer.
(iv) Endosmosis is phenomenon where cell vacuole gains water under hypotonic conditions.
(v) Plasmolysis is the shrinkage of protoplasm when kept in hypertonic solution.
So, the correct answer is '(ii), (iv) & (v)'.
