Answer

To solve the question regarding the correct sequence of the periods of the Mesozoic Era from earliest to latest, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Mesozoic Era**: The Mesozoic Era is known as the era of middle life and is divided into three main periods: Triassic, Jurassic, and Cretaceous.

- **Jurassic Period**: This period follows the Triassic and occurred around 145 million years ago.
- **Cretaceous Period**: This is the latest period of the Mesozoic Era, occurring approximately 130 million years ago.

3. **List the Periods in Order**: Based on the information above, the correct chronological order from earliest to latest is:
- Triassic
- Jurassic
- Cretaceous

4. **Evaluate the Options**:
- **Option 1**: Jurassic, Triassic, Cretaceous - Incorrect (Jurassic comes before Triassic)
- **Option 2**: Triassic, Jurassic, Cretaceous - Correct (This matches our identified order)
- **Option 3**: Permian, Jurassic, Triassic - Incorrect (Permian is not part of the Mesozoic Era)
- **Option 4**: Devonian, Permian, Jurassic - Incorrect (Both Devonian and Permian are from the Paleozoic Era)

5. **Conclusion**: The correct answer is **Option 2: Triassic, Jurassic, Cretaceous**.
