When parking a manual transmission car downhill on a slope without a raised curb, which gear should be engaged and how should the steering wheels be turned?

1. Engage First gear (1), leave the handbrake off, and turn wheels toward the center of the road
2. Leave the transmission in Neutral (N) and rely solely on the parking brake
3. Engage Fifth gear (5) and turn wheels to the left
4. Engage Reverse gear (R), apply the handbrake firmly, and turn front wheels towards the right-hand road edge
