Correct Answer: Option A — **New Delhi**. **New Delhi** is the accurate answer because DRDO operates under the Ministry of Defence and is headquartered in India’s national capital. This identifying fact establishes its correct connection with headquarters and distinguishes it from the other defence-related choices. Why the other options are incorrect: Option B — **Surface-to-air missile system**: This is actually associated with air-defence missile; specifically, Akash is an indigenous mobile surface-to-air missile weapon system serving the Army and Air Force. Option C — **Multirole air-superiority fighter**: This is actually associated with combat aircraft; specifically, the Su-30MKI is a twin-engine fighter used for air-superiority and multiple combat roles. Option D — **President of India**: This is actually associated with constitutional authority; specifically, the Constitution places the supreme command of the Defence Forces of the Union in the President. Exam Takeaway: Link **New Delhi** with its exact **headquarters** association for fast **Indian Defence GK** revision.
