Vascular cambium is a meristematic layer that cuts off
  • A
    Primary xylem and primary phloem
  • B
    Xylem vessels and xylem tracheids
  • C
    Primary xylem and secondary xylem
  • ✓
    Secondary xylem and secondary phloem
✓

Answer

Correct option: D.
Secondary xylem and secondary phloem
The interfascicular and intrafascicular cambiums merge to create a continuous ring known as the vascular cambium, which triggers intrastellar secondary growth. The cells of the vascular cambium are meristematic, meaning they persistently divide to produce daughter cells. The daughter cells formed inward, toward the pith, develop into secondary xylem elements, whereas those formed outward, toward the cortex, differentiate into secondary phloem elements. Therefore, the correct choice is option D.
