(c) reserve for replenishment of damaged cells of the meristem.
Explanation:
The concept of Quiescent Centre was proposed by Clowes in 1961. On the basis of autoradiographic studies of DNA synthesis in the root tip of zea, he found a reservoir of cells having low DNA, RNA and protein concentration. He called it as Quiescent Centre. They may or may not divide. It is resistant to damages.
