Answer

To solve the question regarding the locations of various respiratory centers, we will analyze each center mentioned and identify their correct anatomical locations.

### Step-by-Step Solution:

1. **Identify the Centers**: The centers we need to locate are:
- Pneumotaxic Center
- Apneustic Center
- Dorsal Respiratory Group
- Ventral Respiratory Group

2. **Locate the Pneumotaxic Center**:
- The Pneumotaxic Center is located in the **pons**. It is responsible for regulating the rate and pattern of breathing.

3. **Locate the Apneustic Center**:
- The Apneustic Center is also located in the **pons**. It plays a role in stimulating the inspiratory center, promoting prolonged inhalation.

4. **Locate the Dorsal Respiratory Group**:
- The Dorsal Respiratory Group is found in the **medulla oblongata**. Its primary function is to control the basic rhythm of breathing.

5. **Locate the Ventral Respiratory Group**:
- The Ventral Respiratory Group is also located in the **medulla oblongata**. It is involved in the control of expiration and inspiration, particularly during increased respiratory demand.

### Summary of Locations:
- **Pneumotaxic Center**: Pons
- **Apneustic Center**: Pons
- **Dorsal Respiratory Group**: Medulla oblongata
- **Ventral Respiratory Group**: Medulla oblongata

### Correct Options:
- Pneumotaxic Center: Pons (Correct)
- Apneustic Center: Pons (Correct)
- Dorsal Respiratory Group: Medulla (Correct)
- Ventral Respiratory Group: Medulla (Correct)

### Final Answer:
The correct answer is Option 1, which states the locations of the centers accurately.
