Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Assertion: The quiescent centre has cells that are metabolically less active as compared to the meristematic cells. This region acts as the reservoir of cells to the meristematic zone.
Reason: As the meristematic initials get damaged, the cells of the quiescent centre become active and start with their meristematic activity.
Hence, the correct answer is 'Both Assertion and Reason are correct and Reason is the correct explanation for Assertion'
