Best answer
The correct choice is (b) Redifferentiation

The best I can explain: Redifferentiation leads to the formation of secondary xylem and phloem. Redifferentiation is the maturation of dedifferentiated cells thereby specializing for a particular function.  Development includes all the changes undergone by a living plant from seed emergence to death. Dedifferentiation is regaining the lost capacity of cells or tissues of plants to divide under special conditions. Differentiation is the division and growth of cells in order to mature.
