A Correct answer
Explanation

In a standard VASI, when you see red lights on the far bar and white lights on the near bar (red-on-white), you're precisely on the correct glide slope. This configuration indicates you're at the proper descent angle for landing. Deviations from this pattern signal that you need to adjust your pitch: more white means climb, more red means descend.
