If you intend to take the third exit (turning left / 270 degrees) at a three-lane roundabout in Bahrain, what is the correct lane choice and signaling procedure?

1. Approach in the right lane with right indicator; switch to left inside the roundabout
2. Approach in the left lane with left indicator on; signal right after passing the exit preceding your destination
3. Approach in the middle lane with no indicator; activate hazard lights when turning
4. Approach in the right lane and circle the entire outer perimeter of the roundabout
