The sequence of events by which a cell duplicates its genome, synthesises other constituents of cells and eventually divides into daughter cells is termed as:

1. Interphase                                   

2. M-phase

3. Karyokinesis + Cytokinesis             

4. Cell cycle

Which one is correct for G₀ stage?
I. It is a quiescent stage
II. In this phase cell cycle is stopped
III. G₀ cells in this stage do not grow or proliferate but metabolically active
IV. G₀ cells can divide in response to some stimulus
(1) All are correct                         

(2) I, II, III are correct

(3) I, II are correct                       

(4) Only I and IV are correct
