D Correct answer
Explanation

It is the meristem, that occurs between permanent tissues. It represents the remnant of the apical meristem. It is particularly common, at the nodal regions. It may also occur, at the base of the leaves. The intercalary meristem also contributes, towards the increase in length, as it brings about elongation, of the internodal regions. It is also responsible, for the formation of branches, at the nodal regions.
