Which one of the following is not a correct ascending order of commissioned ranks in the defence forces of India?

The commissioned ranks in the Indian Armed Forces follow a strict hierarchical structure. In the Indian Army, the ascending order is Lieutenant, Captain, Major, Lieutenant Colonel, Colonel, Brigadier, Major General, Lieutenant General, and General. The Indian Navy follows Sub Lieutenant, Lieutenant, Lieutenant Commander, Commander, Captain, Commodore, Rear Admiral, Vice Admiral, and Admiral. In the Indian Air Force, the correct ascending sequence is Flying Officer, Flight Lieutenant, Squadron Leader, Wing Commander, Group Captain, Air Commodore, Air Vice Marshal, Air Marshal, and Air Chief Marshal. Option 3 is incorrect because it incorrectly places Group Captain before Wing Commander; in the IAF hierarchy, a Wing Commander is equivalent to a Lieutenant Colonel, while a Group Captain is a higher rank equivalent to a Colonel . The President of India serves as the Supreme Commander of these forces [3].
