Answer 1

Answer: (B)

Layers of secondary xylem in a stem

Each year, the tree forms new cells, arranged in concentric circles called annual rings or annual growth rings. These annual rings show the amount of wood produced during one growing season. As the stem grows, complete ring called the cambial ring is formed. Cambial ring leads to the formation of secondary xylem and secondary phloem.

Hence, the correct answer is 'Layers of secondary xylem in a stem'.
