Cells that do not divide further exit G1 phase to enter an inactive stage called _______________.

Correct option is A

Cells that do not divide further exit the G1 phase and enter an inactive stage called the quiescent stage or G0 phase. In this phase, the cells are not actively preparing for division but remain metabolically active. These cells may either stay in this stage for an extended period or re-enter the cell cycle under certain conditions.
Information Booster: The G0 phase is also known as the quiescent phase. Cells in this stage are in a resting or dormant state. Some cells, such as neurons and muscle cells, may remain in the G0 phase permanently, while others can be triggered to re-enter the cell cycle and divide if needed (such as liver cells or stem cells). This phase is important for regulating the growth of tissues and preventing uncontrolled cell proliferation.
Additional Knowledge:
· Inactive G stage: This term is not commonly used in cell cycle terminology.
· Nil Stage: This term is not recognized in the context of cell cycle stages.
· Reverse G stage: This term does not refer to any recognized phase in the cell cycle.
