The correct Answer is:
To determine the plant part based on the given features, we can follow these steps: ### Step-by-Step Solution: 1. **Identify the Features**: The question states that the vascular bundles are radially arranged and that there are four xylem strands showing an exarch condition. 2. **Understanding Vascular Bundles**: Vascular bundles consist of xylem and phloem. In a radial arrangement, the xylem and phloem are organized in a way that they are arranged in a circle around the central pith. 3. **Exarch Condition**: The term "exarch" refers to the arrangement of xylem in which the youngest xylem is located towards the periphery (outer side) and the older xylem is located towards the center. This is a characteristic feature of certain plant structures. 4. **Relate Features to Plant Parts**: The combination of radial arrangement of vascular bundles and the exarch condition of xylem is typically found in the roots of dicotyledonous plants (dicots). 5. **Conclusion**: Based on the features described, the plant part in question is a **dicot root**. ### Final Answer: The plant part described is a **dicot root**.
