The right option is; B) G0 phase
Neurons are in the G0 phase.
The G0 phase is a stage in the cell cycle in which cells do not divide or prepare for division but continue to carry out its normal functions for the rest of the organism's life. This phase is the resting phase of the cell and it is seen either as an extended G1 phase or a different stage that occurs outside of the cell cycle. Cells in the G0 phase include neurons, liver cells and heart muscle cells.
