Structures of dicot root that can dedifferentiate areA. Pericycle    B. Conjunctive tissue    C. Endodermis    D. Cortex

Dedifferentiation is a process of permanent living tissue regaining meristematic activity. Such property is shown by pericycle to form complete cork cambium and a part of vascular cambium and conjunctive tissue that forms bulk of vascular cambium of dicot root during secondary growth.
