Explanation:

When backing up a car, the correct procedure is to look over your right shoulder through the rear window and back up slowly? No, wait, actually, the standard driving procedure for backing up is to look over your right shoulder (for right - hand drive? No, in general, when backing up, you should look over your right shoulder through the rear window and back up slowly? Wait, no, let's recall: the correct method is to look over your right shoulder (in left - hand traffic, maybe? Wait, no, the standard driving safety rule for backing up is to look over your right shoulder through the rear window and back up slowly? Wait, no, the option "Look over your right shoulder through the rear window and back up slowly" – wait, no, the blue option is "Look over your left shoulder...", but that's incorrect. Wait, no, maybe I got it wrong. Wait, the correct answer for backing up a car: when you back up, you should look over your right shoulder through the rear window and back up slowly? No, wait, let's check the options. Wait, the options: the second option is "Look over your right shoulder through the rear window and back up slowly", the third is "Look over your left shoulder...". Wait, no, the correct driving technique for backing up is to turn your head and look over your right shoulder (if you are in a left - hand drive vehicle, the driver is on the left, so to see the rear, you look over the right shoulder through the rear window) and back up slowly. But the blue option is the third one, but that's incorrect. Wait, maybe the question is from a driving test. Wait, no, let's re - evaluate. Wait, the correct answer is the option "Look over your right shoulder through the rear window and back up slowly"? No, the second option is "Look over your right shoulder through the rear window and back up slowly", the third is "Look over your left shoulder...". Wait, maybe I made a mistake. Wait, the correct driving procedure for backing up: when you put the car in reverse, you should look over your right shoulder (for a left - hand drive car, the driver's seat is on the left, so the rear window is behind, and to get a clear view, you look over the right shoulder) and back up slowly. So the correct option is the second one: "Look over your right shoulder through the rear window and back up slowly". But the blue option is the third one, which is incorrect. Wait, maybe the question has a different context. Wait, no, let's check the options again. The options are:

1. Use both rearview mirrors – not sufficient, as blind spots exist.

1. Look over your right shoulder through the rear window and back up slowly – this is the correct driving technique for backing up, as it allows you to see directly behind the car, especially for the area not visible in the mirrors.

1. Look over your left shoulder through the rear window and back up slowly – incorrect, as the driver's position (in left - hand drive) makes looking over the right shoulder more effective for rear visibility.

1. Turn your head from side to side quickly so you can look over both shoulders – not the standard procedure, as you need a steady view behind.

So the correct option is the second one: "Look over your right shoulder through the rear window and back up slowly".

Answer:

B. Look over your right shoulder through the rear window and back up slowly
