Answer:
Correct Answer: A
Solution:
Intercalary meristems are intercalated in-between the permanent tissues.
The activities of these meristems also add to the length of the plant or its organs.
They originate from the apical meristems when their portions get detached due to the growth of the organs.
For example, in the grasses when the internodes complete their elongation, some cells at the base retain their meristematic activity and function as intercalary meristems.
They lie just above the node.
