Answer 2

Answer:

The correct option for A is Phellem.

Explanation:

• A meristem constitutes the actively dividing cells with enriched protoplasm concerned with the formation of new cells. it may be primary or secondary.

• Secondary meristems are those which suspend their ability to divide and again resume it when needed.

• Secondary meristem is responsible for secondary growth in plants i.e. the growth in thickness or girth

• It is also responsible for giving rise to the cells differentiating into secondary permanent tissues i.e. phellem(Cork cambium).

• And activities in the cambial ring give rise to secondary xylem and secondary phloem during secondary growth.

Hence the formation of phellem occurs due to the activity of secondary meristem only.
