• A. Cortex
• B. Pericycle
• C. Epidermis
• D. Vascular bundle

Answer 1

Answer: (A)

Cortex

In a dicot stem, cork cambium arises from cortex. Cork cambium is found in vascular plants. The cork cambium is a lateral meristem which is responsible for secondary growth in roots and stems. It replaces the epidermis. It is found in dicots, gymnosperms and some monocots. Outermost layer of cortex is modified to cork cambium.

Thus, the correct answer is option A.
