Answer:
The ‘growth rings’ are formed due to the activity of B) Intra-stelar cambium.
Explanation:
In between the ‘xylem and phloem’ of the dicot stem lies the Intrastelar cambium. The fascicular cambium begins to divide and new cells are produced on the both outer and the inner sides.
At the same instance some parenchymatous cells of medullar rays form meristematic in the same line with fascicular cambium of vascular bundle and join the later to form the cambium ring.
