Structures of dicot root that can dedifferentiate during normal secondary growth  are
A. 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.
