The question presents an analogy based on military ranks. We need to identify the relationship between Major and Lieutenant and apply the same relationship to Squadron Leader to find the corresponding rank.
Major and Lieutenant are ranks in many armed forces, including the Indian Army. Lieutenant is a junior rank to Major. Specifically, in a typical hierarchy, a Major is senior to a Captain, who is senior to a Lieutenant. So, Lieutenant is two ranks below Major.
Now, let's consider the ranks in the Indian Air Force. Squadron Leader is a rank equivalent to a Major in the Army. We need to find the rank that is two levels below Squadron Leader. The ranks in the Indian Air Force, in ascending order, are generally:
Flying Officer
Flight Lieutenant
Squadron Leader
Wing Commander
Group Captain
...
Following this hierarchy, Flight Lieutenant is one rank below Squadron Leader, and Flying Officer is two ranks below Squadron Leader.
Therefore, Major is related to Lieutenant in the same way as Squadron Leader is related to Flying Officer.
