Correct Answer: Option C — **15 January**. **15 January** is the accurate answer because the day commemorates Lieutenant General K. Cariappa taking over as the first Indian Commander-in-Chief of the Indian Army in 1949. This identifying fact establishes its correct connection with commemorative day and distinguishes it from the other defence-related choices. Why the other options are incorrect: Option A — **Dundigal, Telangana**: This is actually associated with training institution; specifically, the academy provides pre-commission training for Indian Air Force officer trainees. Option B — **Anti-tank guided missile**: This is actually associated with anti-armour missile; specifically, Nag was developed as an indigenous guided missile for engaging armoured targets. Option D — **Attack helicopter**: This is actually associated with rotary-wing combat platform; specifically, Apache is a dedicated attack helicopter designed for armed reconnaissance and engagement of ground targets. Exam Takeaway: Link **15 January** with its exact **commemorative day** association for fast **Indian Defence GK** revision.
