- Narmada
- Tapi
- Damodar

3. **Analyze the Given Options**:

- These rivers are located in southern India but do not flow through rift valleys. Therefore, this option is incorrect.
- **Option 2: Narmada and Tapi**:
- Both of these rivers are known to flow through rift valleys in India. This option is correct.
- **Option 3: Ganga and Yamuna**:
- Ganga originates from the Himalayas and Yamuna is its tributary. Neither of these rivers flows through a rift valley, making this option incorrect.
- **Option 4: Satluj and Ravi**:
- These rivers are also Himalayan rivers and do not flow through rift valleys. Hence, this option is incorrect.

4. **Conclusion**:
