Equivalence of ranks: Brigadier is equivalent to Air Commodore in IAF and Commodore (not Commander) in the Navy — so 1 is wrong. Major General is equivalent to Air Vice Marshal and Rear Admiral (not Vice Admiral) — so 2 is wrong. Major is equivalent to Squadron Leader in IAF and Lieutenant Commander in the Navy — so 3 is correct. Lieutenant Colonel is equivalent to Wing Commander in the IAF and Commander in the Navy, not Group Captain/Captain — so 4 is wrong. Only pairing 3 is correctly matched.
