The correct option is A A-3, B-1, C-2, D-4
The root apical meristem, or root apex, is a small region at the tip of a root in which all cells are capable of repeated division and from which all primary root tissues are derived.
The root apical meristem is protected as it passes through the soil by an outer region of living parenchyma cells called the root cap.
Secondary, or lateral meristems, which are found in all woody plants and in some herbaceous ones, consist of vascular cambium and the cork cambium.
They produce secondary tissues from a ring of vascular cambium in stems and roots.
The meristem present at the base of internodes is intercalary meristem.
The cork cambium also is a secondary meristem, containing meristematic cells. The cork cambium forms a major portion of the bark of woody plants.
The secondary phloem also is part of the bark, but of course phloem is produced by the vascular cambium.
