The Indian Navy is the correct answer because it successfully completed expeditions to all three poles - the South Pole, North Pole, and Mount Everest.

The other options (US Air Force and British Navy) have not accomplished this specific three-pole conquest.

During 2009-10, the Indian Navy adopted the theme 'Power-Packed Force for a Strong Nation' as its motto. This was part of the Navy's public communication and recruitment efforts to emphasize its role in national security. Each branch of the armed forces periodically adopts themes or mottos for specific years to highlight their capabilities and commitment to the nation's defence. The Indian Army and Air Force have their own distinct themes for different periods.

INS (Indian Naval Ship) Kadamba, will be the first operational base with a port controlled exclusively by the Navy, allowing it to position and manoeuvre its operational fleet without worrying about the movement of merchant vessels. Indian Navy's existing bases, including its two operational ones in Mumbai and Vishakhapatnam, are located in enclaves within commercial ports, making for an unsuitable situation especially in times of war. The Rs.35,000-crore fully integrated INS Kadamba is expected to be the biggest naval base this side of the Suez Canal.

The Court of Inquiry (Col) into the Darjeeling land scam case has revealed that a Siliguri real estate developer and one of the seniormost generals in the Army were in constant touch while a dubious Memorandum of Understanding (MoU) was being drafted to clinch the land deal. The Col has established through phone records that real estate developer Dilip Agarwal, who inked the MoU to obtain No Objection Certificates from the Army for 71 acres near the 33 Corps HQ in Sukna Cantonment, was in constant touch with Lt Gen Avadhesh Prakash, Military Secretary (MS) at Army HQ, New Delhi while the deal was being sealed. Lt Gen Prakash did not have a direct role in granting the NOCs but the Col says that he used his influence as one of the seniormost officers in the Army to ensure that the deal went through. The case unravelled after it came to light that a massive land deal in Sukna was cleared by the Army against norms.
