The correct answer is suspend, since cells exit G1 phase. Please refer to my comment down below, or refer to latest NCERT page 164.

Thank you.

Is the question regarding the G0 phase?

If yes, then then the answer is the cells exit cell cycle.It is because the cells in G0 phase have the ability to undergo cell division if necessary , ie, to replace any dead cells. So we cannot say they suspend cell cycle.If they do these cells will never undergo cell division again.Which is why the answer is exit cell cycle.

Hope the answer helped.
