The Treasury Single Account system launched in the Ministry of Defence is integrated with which platform of the Reserve Bank of India?

The correct answer is the 279th Annual Day. The Raksha Mantri launched the department’s publications and digital initiatives at this celebration held at DRDO Bhawan in New Delhi, and he congratulated the department on nearly three centuries of service to the nation, which fits an edition in the high two hundreds. Options A, B and D are near neighbours offered because an edition number is easy to misremember by a decade; none of them is the figure for this year. A useful cross-check for an aspirant is the phrase about three centuries of service, which rules out any edition in the low two hundreds. Also note the venue, DRDO Bhawan, which is sometimes swapped with South Block or Sena Bhawan in a question. So C is correct.

The correct answer is managing pay and allowances of Agniveers of the Indian Army. SAMAR-SETU runs from the Central Agniveer Pay and Accounts Office and handles the pay accounts of more than 2.3 lakh Agniveers through fully automated processes, which is why work on it figured in the Raksha Mantri Awards for Excellence 2026. Option A describes the National Compilation System, the single source for accounting and compilation of all defence expenditure, which was relaunched in a revamped form at the same event. Option C points to SAKSHAM, the bill audit and payment system now integrated with the Indian Army Financial Information System. Option D describes SPARSH, the System for Pension Administration (Raksha). Separating these four names is exactly what an examiner wants to test, so B is right.

The correct answer is Trishakti Manthan held as a permanent annual review body. Trishakti Manthan was the event organised as part of the Silver Jubilee, featuring addresses by the Chief of Defence Staff and by the Chief of Integrated Defence Staff, and it is not described as a standing institutional mechanism of the kind listed in the other options. Option A is wrong as an answer because Ran Samwad is indeed named among the platforms that strengthen institutional mechanisms for jointness. Option B is wrong as an answer for the same reason, the Joint Commanders’ Conference being one of those platforms. Option C is likewise a genuine platform, the Combined Operational Review and Evaluation Programme, which supports structured deliberation on security challenges and improves joint warfighting across land, maritime, air, space, cyber and cognitive domains.

The correct answer is “Future readiness through jointness and Integration”. Under this theme HQ IDS organised Trishakti Manthan, released a Silver Jubilee Book and a film on its milestones, and conferred CDS Unit Citations on personnel. Option A is wrong because Atmanirbharta in defence is the wider national goal that HQ IDS supports by working with research organisations, academia and industry on indigenous capability, but it was not the jubilee theme. Option C is wrong because joint training frameworks were only one of the contributions discussed at the event and no such slogan was adopted. Option D is wrong because cyber and space are among the emerging domains the organisation prepares the forces for, yet neither phrase formed the theme. Themes are a favourite one-mark question, so the exact wording matters.

The correct answer is 1 October 2001. HQ IDS was established in New Delhi on that date, and the day is observed every year as Tri-Service Day; the organisation therefore completed 25 years and celebrated its Silver Jubilee under the theme of future readiness through jointness and integration. Option B is wrong because the body did not exist in that year, and an earlier date would not fit a Silver Jubilee falling now. Option C is wrong because that date belongs to no part of this story, and the founding was in October, not January. Option D is wrong because the post of Chief of Defence Staff and the Department of Military Affairs came much later than the raising of HQ IDS, so a date from this decade cannot be its founding day. Fix the date along with the name Tri-Service Day.
