Which of the following statements related to G0 stage of the cell cycle are correct?(i) It is a quiescent stage.(ii) In this phase, cell cycle is stopped.(iii) G0 cells do not grow or proliferate but metabolically active.(iv) G0 cells can enter into cell cycle and divide in response to some stimulus.

All the statements regarding Go stage of the cell are correct. Go stage or resting phase is a period in the cell cycle in which cells exist in a quiescent state. Go phase is viewed as either an extended G1 phase, where the cell is neither dividing nor preparing to divide, or a distinct quiescent stage that occurs outside of the cell cycle. Some (like cells, nerve and heart muscle cells), become quiescent when they reach maturity (i.e., when they are terminally differentiated) but continue to perform their main functions for the rest of the organism's life.
