Name the stage which is physiologically the most active stage but looks to be restive.

Explanation

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

1. **Understanding the Cell Cycle**: The cell cycle consists of several phases, primarily divided into Interphase and M phase (Mitotic phase).

2. **Identifying Interphase**: Interphase is the phase where the cell prepares for division. It is often referred to as the "resting stage" because the cell is not actively dividing.

3. **Physiological Activity During Interphase**: Despite being called a resting stage, Interphase is the most physiologically active stage of the cell cycle. During this phase, several critical processes occur:
- **Synthesis of Enzymes**: The cell produces various enzymes necessary for metabolic functions and cell division.
