The correct option is B shoot apical meristem
The meristematic tissues are responsible for the formation of the primary plant body which includes the root, stem and leaves.
The root apical meristem forms the root and the shoot apical meristem forms the stem and leaves.
The lateral meristems increase the girth of the plant in the later stages of growth.
Intercalary meristems are usually found in grasses in between the nodes of the stem and the base of the leaves.
