Which one of the following recently became the only organization in the world to have conquered all three poles - the conventional South and North Poles besides Mt. Everest?

The Indian Navy is the correct answer because it successfully completed expeditions to all three poles - the South Pole, North Pole, and Mount Everest. This unique achievement demonstrates their extensive exploration capabilities across extreme terrains. The other options (US Air Force and British Navy) have not accomplished this specific three-pole conquest.
