To determine which statement is correct, we need to analyze the options provided in the question.
1. **Understanding the Options**:
- The first option states that in potato, banana, and ginger, the plant that arises from the internode is a modified stem.
- The second option claims that water hyacinth growing in standing water drains oxygen from the water, leading to the death of fishes.
2. **Analyzing Option 1**:
- In the case of potato, banana, and ginger, these plants do indeed have modified stems.
- Potatoes have tubers, bananas have pseudostems, and ginger has rhizomes, which are all types of modified stems that arise from the internode.
- Therefore, this statement is correct.
3. **Analyzing Option 2**:
- Water hyacinth is known to grow in standing water and can indeed reduce the oxygen content in the water.
- It competes for resources such as air, minerals, and light, which can lead to the decline of other aquatic plants.
- As these plants die off, the biomass increases, which can lead to pollution and further depletion of oxygen, ultimately causing the death of fishes.
- This statement is also correct.
4. **Conclusion**:
- Both statements appear to be correct based on the analysis. However, since the question asks for the correct statement and the video emphasizes the second option, we can conclude that the second statement is the one highlighted as correct in the context of the video.
**Final Answer**: The correct statement is that water hyacinth growing in standing water drains oxygen from the water, leading to the death of fishes.
