The correct option is B Redifferentiation
The living differentiated cells, that have lost the capacity to divide
can regain the power of division under certain conditions, this
phenomenon is termed as de-differentiation. E.g.,formation of
meristerns-interfascicular cambium (Formed from medullary rays) and cork
cambium (formed from outer layer of cortex) from fully differentiated
parenchyma cells. While doing so, such meristems/tissues are able to
divide and produce cells that once again lose the capacity to deride but
mature to perform specific functions, i.e., get redifferentiated. E.g.,
cells of secondary xylem, secondary phloem, periderm. Thus
rediffrentiation can be defined as maturation or differentiation of
dedifferentiated tissues. So, the correct answer is 'Redifferentiation'.
