Dicot stem
D

Answer
Dicot root
Explanation
Solution
The correct option is (A) : Dicot root
A radial vascular bundle, also known as a radial bundle, is a vascular bundle in which the principal xylem and primary phloem strands are placed on alternating radii of an axis and are isolated from one another by non-vascular tissues. The distinctive feature of roots is their bundles. The secondary thickening is carried out by the secondary cambium, which only develops at the time of secondary growth in dicotyledonous roots, as there is no primary cambium in this bundle. In contrast to monocot roots, which often have many xylem poles (more than six), dicot roots typically contain four to six protoxylem poles.
