The cork cambium produces
A
vascular cambium
B
cork in the vascular cambium
C
cork in the xylem
D
cork in the bark layer
Explanation: 

Detailed explanation-1: -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. The cork cambium first arises within the cortex as a concentric layer forming a cylinder of dividing cells (Fig. 1.9).

Detailed explanation-2: -The cork cambium is involved in the production of cork – a tough protective matter. The cork cambium or pericambium or Phellogen initially forms from the parenchyma cells in the cortex and at times in the primary phloem.

Detailed explanation-3: -plant growth The cork cambium, or phellogen, produces the protective outer layers of the bark.

Detailed explanation-4: -Cork cambium (pl. cambia or cambiums) is a tissue found in many vascular plants as a part of the epidermis. It is one of the many layers of bark, between the cork and primary phloem. The cork cambium is a lateral meristem and is responsible for secondary growth that replaces the epidermis in roots and stems.
