Answer:
Correct Answer: D
Solution:
Intercalary meristems are intercalated in between the permanent tissues.
They may be present either at the base of the internode as in the stems of various grasses and wheat; or at the base of the leaf as in Pinus; or at the base of a node as in mint (Mentha viridis).
Usually the intercalary meristems differ from other meristems in that they ultimately get fully used up in the formation of permanent tissues.
