Answer 1

Answer: (B)

Secondary cortex and cork

Cork cambium is a tissue found in many vascular plants as part of the epidermis. The cork cambium is a lateral meristem and is responsible for secondary growth that replaces the epidermis in roots and stems. It gives rise to cork outside and secondary cortex inside.

Hence, the correct answer is 'Secondary cortex and cork'.
