Correct Answer : B.
In most dicot stems and roots, secondary growth occurs due to addition of secondary tissues (secondary cortex, secondary phloem and secondary xylem) formed by the activity of vascular cambium in the stelar region inside pericycle and cork cambium in the extrastelar regions (region outside pericycle i.e., cortex)
