Kargil Vijay Diwas is observed every year on which date?

The correct answer is A, 15 January. On this day in 1949 Field Marshal K. M. Cariappa took over as the first Indian Commander in Chief of the Indian Army, and the day is marked with a parade and the presentation of gallantry awards. Option B is wrong because 26 January is Republic Day, the day the Constitution came into force in 1950, and although the armed forces take part in its parade it is not the day of the army. Option C is wrong because 8 October is Air Force Day, the day on which the Indian Air Force was raised in 1932. Option D is wrong because 4 December is Navy Day, kept for the attack on Karachi harbour in 1971. Papers place the three service days in one question, so read which force is named.

The correct answer is B, Operation Trident. During the war of 1971 Indian missile boats struck Karachi harbour in an action that sank enemy vessels and set the oil installations on fire, and 4 December is kept as Navy Day in memory of it. Option A is wrong because the raising of the force belongs to a different date and the day is not an anniversary of its establishment, unlike Air Force Day. Option C is wrong because the commissioning of a carrier is a separate event in naval history and no day of remembrance is attached to it. Option D is wrong because the naval uprising of 1946 is an important episode of the freedom struggle but is not what this day marks. Tie 4 December to Karachi and the pair is fixed.

The correct answer is B, officially raised. The Indian Air Force was constituted on 8 October 1932 and its first flight took to the air in the following year, which is why the day is kept as the anniversary of the force itself and is marked by a display at an air force station. Option A is wrong because the raising of the first squadron followed the creation of the force and is not the reason for the date. Option C is wrong because the change of name relates to a later period, when the prefix Royal was dropped after independence, and no day is kept for it. Option D is wrong because the appointment of the first Indian chief came in 1954 and is remembered as a separate landmark. Hold 8 October with the year 1932.

The correct answer is C, 7 December. Armed Forces Flag Day has been observed since 1949, when it was decided that the country should contribute to the welfare of serving personnel, veterans and the families of those killed in service, and small flags are distributed in return for contributions. Option A is wrong because 1 December is the raising day of the Border Security Force. Option B is wrong because 4 December is Navy Day, kept for Operation Trident of 1971. Option D is wrong because 16 December is Vijay Diwas for the victory of 1971. December is the most crowded month in this topic, holding four separate days, so a candidate should revise the month as a block and not one day at a time.

The correct answer is A, Hot Springs in Ladakh. A small patrol of the Central Reserve Police Force was ambushed there in October 1959 and several policemen were killed, and since then 21 October has been kept as the day on which the country remembers all police personnel who died on duty during the year. Option B is wrong because the Rann of Kutch is associated with the border clash of 1965 and with the wild ass sanctuary, not with this day. Option C is wrong because the Tawang sector belongs to the fighting of 1962 in the eastern Himalaya, a different theatre and a different year. Option D is wrong because the Chambal ravines are connected with campaigns against dacoity and with no day of remembrance of this kind.
