Suspend the cell cycle is correct because g0 phase cell are not exist the cell due to reversible nature of division are still appriciable

DO CHALLENGE THE QUESTION MORE AND MORE ! THE ANSWER SHOULD BE 'EXIT THE CELL CYCLE' EXPLAINATION: in updated NCERT FIG 10.1 PAGE NO.163 G0 is clearly shown to be outside the cell cycle. Further there are 2 types of G0 cells- Reversible and Irreversible. Reversible ones can continue the cell cycle but majority are irreversible which EXIT cell cycle permanently.

Suspend the cell cycle is correct, because according to English dictionary suspend mean to stop something from being active temporarily or permanently. So the cells in the cell in the G0 phase suspend the cell cycle but not exit 

If its answer according to 10yrs ago is suspend ....but ncert has now been updated

Then in previously asked qstion spirulina was in ALGAE in food supplements...

But now spirulina is not there

Yes ncert me likha hai    exit G1 phase.

But ye b to nhi likha khi.

K suspend cell cycle.

According to ncert, those cells that do not divide further EXIT G1 PHASE and enter into G0 phase.

It does not say that these cells will exit the  CELL CYCLE.
