ILS stands for which system?

Explanation:
An Instrument Landing System is a precision approach aid that provides both lateral and vertical guidance to pilots during instrument flight rules conditions. The localizer supplies horizontal guidance to keep the aircraft aligned with the runway centerline, while the glideslope delivers vertical guidance to set the proper descent angle for a stable approach and landing. This combination lets a pilot fly an accurate path to a safe touchdown even with low visibility, aided by approach lighting and markers as needed. That’s why the term Instrument Landing System is the correct expansion. The other phrases don’t correspond to established aviation systems used for landing guidance.
