**Rearview mirrors** are essential elements in a vehicle that allow the driver to see what is happening on the sides and behind the vehicle. There are two main types of mirrors: **interior** and **exterior**.

- **Interior mirrors**: These are located inside the vehicle, usually in the central part, above the front glass. These mirrors help to see what is happening directly behind the vehicle.

- **Exterior mirrors**: These are located outside the vehicle, on the left and right sides. The left-side mirror is mandatory, while the right-side mirror is recommended but not always mandatory.

Therefore, a vehicle can have both **interior and exterior mirrors**, which confirms that the correct answer is option 1: **Interior and exterior**.
