Answer:
Correct Answer: D
Solution:
All the statements regarding $ G_{o} $ stage of the cell are correct.
$ {G_{o}} $ stage or resting phase is a period in the cell cycle in which cells exist in a quiescent state.
$ {G_{o}} $ phase is viewed as either an extended $ {G_1} $ 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 nerve, cells 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.
