The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Xerophytes**: Xerophytes are plants adapted to survive in dry and arid conditions where water is scarce. They have specialized structures and mechanisms to minimize water loss and maximize water uptake. 2. **Osmotic Concentration**: Osmotic concentration refers to the concentration of solutes in a solution, which affects the movement of water. In plants, the osmotic concentration of cell sap is crucial for maintaining turgor pressure and overall plant health. 3. **Comparison with Aquatic Plants**: In aquatic plants, the osmotic concentration is generally lower because they are surrounded by water, which allows them to maintain a higher water potential. In contrast, xerophytes need to retain as much water as possible due to their environment. 4. **Higher Osmotic Concentration in Xerophytes**: In xerophytes, the osmotic concentration of cell sap is higher than in normal conditions. This is because they accumulate solutes in their cells to lower the water potential, allowing them to retain water more effectively in dry conditions. 5. **Conclusion**: Therefore, the osmotic concentration of cell sap in xerophytes is higher than normal, making the correct answer option C. ---
