Correct Answer
Detailed Explanation
The second option is correct as the interfascicular cambium is formed from medullary rays, as stated in the NCERT context. The cambium is generally more active on the inner side, producing more secondary xylem, and spring wood is lighter and less dense than autumn wood. Bark includes multiple tissue types, not just secondary phloem and cork cells.
