In ILS terminology, LOC is primarily associated with which function?

Explanation:
The Localizer provides horizontal, or lateral, course guidance to the runway centerline. It transmits a signal that shows how far you are from the intended course and which way to steer to center the path, so you can stay aligned with the runway. When paired with the glideslope, you get both lateral and vertical guidance, commonly referred to as LOC/GS. Distance information and altitude are provided by other elements (DME/markers for distance, glideslope for vertical), and visual cues are outside the instrument approach. So the primary function associated with LOC is course guidance.
