Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Cells in the G₀ phase of the cell cycle do not proliferate but remain metabolically active. Reason (R): Cells that do not divide further exit the S phase to enter an inactive stage called the quiescent stage. In the light of the above statements, choose the most appropriate answer from the options

Step-by-step solution

Assertion (A) is true because cells in the G₀ (quiescent) stage remain metabolically active but no longer proliferate unless called on to do so depending on the requirement of the organism. Reason (R) is false because according to NCERT, cells that do not divide further exit the G₁ phase (not the S phase) to enter the inactive stage called the quiescent stage (G₀ ) of the cell cycle. Therefore, Assertion (A) is true but Reason (R) is false. Answer: Assertion (A) is true but Reason (R) is false
