(c) Initial and final approach fix

(d) ILS

The question was asked during an interview.

This is a very interesting question from Mechanics of Landing topic in chapter Landing Systems & Air-Traffic Management of Avionics

Answer 1

Correct answer is (c) Initial and final approach fix

The best I can explain: Approach altitudes are measured barometrically and the transition flight path is defined by initial and final approach fixes using Tacan and marker beacons. Radar vectors can also be used at times.
