The correct answer is Appointments Committee of Cabinet. The Chief of the Army/Navy/Air Force is appointed by the Appointments Committee of the Cabinet (ACC). It is a central government committee that comprises the Prime Minister, the Minister of Home Affairs, and the Defence Ministry. The chiefs of respective forces reach superannuation by up to three years at the office or at the age of 62 years, whichever is earlier. The Narendra Modi government amended the Army, Navy, and Air Force Service Regulations to change the framework for eligibility for the post of Chief of Defence Staff. The earlier amendment of 28 December 2019 had restricted the eligibility to serving Chiefs of the three Services. As per the amendment on June 6, 2022, all serving three-star and retired three-star officers who would not reach 62 years of age on the date of appointment are eligible for the post of CDS.
