A tri-color Visual Approach Slope Indicator (VASI) provides essential information to pilots regarding their approach to a runway by utilizing three colors: red, green, and amber. The correct interpretation of this system indicates that a green light represents the ideal glide path or proper approach slope (on glide path), red signifies that the aircraft is below the desired glide path (too low), and amber (or yellow) indicates that the aircraft is on a descent but above the glide path (too high).

With this understanding, option B is correct because it accurately describes the tri-color VASI system: green for being on the correct glide path, red for being below the glide path, and amber for being above it. The consistency of these color indications is critical for pilots to make safe landing approaches, which reinforces why understanding the color meanings is vital in aviation operations.
