How should a driver position their vehicle and signal when taking the first exit (turning right) at a standard multi-lane roundabout?

1. Approach in the leftmost lane, signal left, cut across all lanes, and exit without signaling
2. Approach in the middle lane with hazard lights flashing, and turn sharply right
3. Approach in the right lane with left indicator on until after exiting
4. Approach in the right-hand lane, signal right on approach, maintain the outer lane, and exit with the right signal on
