Best answer
The correct answer is (b) differentiation

The best explanation: Differentiation is responsible for the vacuolization and development of end wall perforation in sieve tube elements. Differentiation is the division and growth of cells in order to attain maturity.  Dedifferentiation is regaining the lost capacity of cells or tissues of plants to divide under special conditions. 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.
