The correct option is
C
Intercalary meristem
Intercalary meristems are residual apical meristems present at the nodes and internodes which increases the length of the plant
A slender stalk-like structure which joins the leaf blade to the stem is known as a petiole.
A petiole is formed by the transitional part of the plant (between the stem to the leaf blade).
The increase in the length of the petiole is due to the activity of the intercalary meristems.
So, the correct answer is 'Intercalary meristem'.
