Options

A. primary xylem and primary phloem
B. secondary xylem and secondary phloem
C. primary xylem and secondary phloem
D. secondary xylem and primary pholem

Answer

b

Explanation

Vascular cambium is formed by fascicular and interfascicular cambium . It leads to secondary growth in dicot roots and dicot stems . Cells of vascular cambium , known as fusiform initially produce secondary phloem on the outside and secondary xylem on the inner side.
Youngest xylem layer occur inner to vascular cambium while oldest layer of secondary xylem is found outside the primary xylem or towards pith . In case of phloem lies just outside the vascular cambium while oldest layer is towards outside , inner to primary phloem.
