Solution
The correct option is C Cambium
The inter and intrafascicular cambiums join to form a complete ring of cambium called as vascular cambium, which initiates interstellar secondary growth. The vascular cambial cells continuously divide and the cells produced inward towards pith mature into secondary xylem elements, while those produced outward toward cortex differentiate into secondary phloem elements. Secondary growth in dicot stem occurs by an increase in lateral thickening which increases the girth of the plant.
Thus, the correct answer is option B.
