Correct answer
B. many xylem bundles
Step-by-step solution
The vasculature is radial in dicot root i.e., xylem bundles alternate with phloem bundles. Usually vascular bundles are 2-6 in number while in monocot root the vascular strand consists of several ( 8 or more) alternate radial xylem and phloem bundles. Secondary growth takes place in dicot root while absent in monocot roots and annual rings do not form.
