Correct answer
A. (A) - (III), (B) - (I), (C) - (II)
Step-by-step solution
(A) Tracheary elements are formed from primary meristems whose cells undergo maturation and lose their protoplasm to become dead at maturity. This process of maturation is called differentiation. (B) Cork cambium is a secondary meristem formed from living permanent cells (like cortical cells) that regain the capacity to divide. This regaining of division capacity is called dedifferentiation. (C) Secondary xylem is formed from the vascular cambium (a dedifferentiated tissue). The derivatives of vascular cambium lose
