Options

A. Increae
B. Decrease
C. Remain the same
D. None.

Answer

**Step-by-Step Solution:**

1. **Understanding Auxin**: Auxin is a plant hormone that plays a crucial role in various plant growth processes, including root development and water absorption.

2. **Location of Auxin Production**: Auxin is produced in the growing tips of plants, which include both the shoots above ground and the roots below ground.

3. **Effect of Auxin on Root Development**: Auxin promotes root formation, which means that higher concentrations of auxin can lead to the development of more roots or an increase in root area.

4. **Increased Root Area**: With an increase in the area of the roots due to auxin, the roots can absorb more water and minerals from the soil.

5. **Conclusion on Water Absorption**: Therefore, if the concentration of auxin is increased in plant roots, the water absorption will increase because of the enhanced root area that facilitates greater uptake of water.

6. **Final Answer**: The correct conclusion is that the water absorption will increase.
