The phase in which cells fail to divide further (do not undergo S- phase after G1 -phase) is known as G0 phase or quiescent stage. It occurs due to non-availability of mitogen and energy rich compounds. The cells remain metabolically active, but no longer proliferate unless called on to do so depending on the requirement of the organisms.

Q. Assertion :Some cells enter G0​ phase leading to inactivation of cell cycle. Reason : G0​ phase occurs due to non-availability of mitogen and energy rich compounds.

If both assertion and reason are true and reason is the correct explanation of assertion

If both assertion and reason are true but reason is not the correct explanation of assertion

If assertion is true but reason is false

If both assertion and reason are false

Q. Assertion :Some cells enter $G_{0}$ phase leading to inactivation of cell cycle.
Reason : $G_{0}$ phase occurs due to non-availability of mitogen and energy rich compounds.
