- C. In potato, banana, and ginger, the plantlets arise from the internodes present in the modified stem
- D. Water hyacinth, growing in the standing water, drains oxygen from water that leads to the death of fishes
Explanation
Potato, banana, and ginger propagate vegetatively by their modified stems. Potato propagates by tuber which has buds over its eyes or nodes. These buds produce new plantlets. Bananas and ginger propagate with the help of rhizomes which also have buds on nodes for the formation of new plantlets.
