Area where root thickens, procambium changes into the specialized cells of the xylem, phloem, and vascular cambium, and root hairs emerge.
A
Zone of Differentiation
B
Zone of Elongation
C
Zone of Initiation
D
Zone of Emergence
Explanation: 

Detailed explanation-1: -Procambial cells are differentiated to xylem and phloem components.

Detailed explanation-2: -The procambium is located next to the protoderm. The procambium gives rise to cells that make up the primary xylem and the primary phloem. Aside from the primary vascular tissues, the vascular cambium and the cork cambium may also arise from the procambium.

Detailed explanation-3: -There are three primary meristems: the protoderm, which will become the epidermis; the ground meristem, which will form the ground tissues comprising parenchyma, collenchyma, and sclerenchyma cells; and the procambium, which will become the vascular tissues (xylem and phloem).

Detailed explanation-4: -Procambium lies just inside of the protoderm and develops into primary xylem and primary phloem. It also produces the vascular cambium and cork cambium, secondary meristems.
