Quiescent stage is characterized by

Options

A. Metabolically inactive cells
B. Metabolically active cells
C. Proliferating cells
D. Cells under division

Answer

### Step-by-Step Solution:

1. **Understanding the Quiescent Stage**: The quiescent stage, also known as the G0 phase, is a part of the cell cycle where cells are in a state of dormancy. They are not actively dividing but are metabolically active.

2. **Analyzing the Options**:
- **Option 1: Metabolically Inactive Cells**: This option suggests that cells in the quiescent stage are inactive. This is incorrect because quiescent cells are still metabolically active, even though they are not dividing.

- **Option 2: Metabolically Active Cells**: This option indicates that cells in the quiescent stage are active at the metabolic level. This is correct as quiescent cells perform various functions and maintain their metabolic processes.

- **Option 3: Proliferating Cells**: This option refers to cells that are actively dividing. This is incorrect because quiescent cells are not in the process of proliferation.

- **Option 4: Cells Under Division**: This option implies that cells in the quiescent stage are dividing. This is also incorrect, as cells in the quiescent stage are not undergoing division.

3. **Conclusion**: Based on the analysis of the options, the correct characterization of the quiescent stage is that it is represented by **metabolically active cells** (Option 2).

### Final Answer:
The quiescent stage is characterized by **metabolically active cells**.
