The stage of cell cycle when cell decides to undergone differentiation is

Explanation

**Step-by-Step Text Solution:**

1. **Understanding the Cell Cycle**: The cell cycle is a series of phases that a cell goes through as it grows and divides. It consists of interphase (which includes G1, S, G2 phases) and the mitotic phase.

2. **Identifying the Phases of Interphase**: Interphase is divided into three main phases:
- G1 phase (Gap 1): The cell grows and synthesizes proteins.
- S phase (Synthesis): The cell duplicates its DNA.
- G2 phase (Gap 2): The cell continues to grow and prepares for division.
