Verified by Toppr

In monocot roots, the protoxylem elements face pericycle between xylem and phloem elements, parenchyma cells are present constituting conjunctive tissue. This tissue does not become meristematic. Vascular bundles are usually more than six in number. Hence, the vascular bundle is radial with exarch xylem.
Thus, the correct answer is option B.
