Which operation is associated with India securing key positions on the Siachen Glacier in 1984?

Correct Answer: Option A — **Operation Meghdoot**. **Operation Meghdoot** is the accurate answer because Operation Meghdoot was launched in April 1984 for control of strategic heights in the Siachen area. This identifying fact establishes its correct connection with military operation and distinguishes it from the other defence-related choices. Why the other options are incorrect: Option B — **Varuna**: This is actually associated with naval exercise; specifically, Varuna is the established bilateral maritime exercise of the Indian and French navies. Option C — **General Bipin Rawat**: This is actually associated with historic appointment; specifically, he assumed office as the first Chief of Defence Staff on 1 January 2020. Option D — **Supersonic cruise missile**: This is actually associated with cruise missile; specifically, BrahMos is a supersonic cruise missile developed through an India–Russia joint venture. Exam Takeaway: Link **Operation Meghdoot** with its exact **military operation** association for fast **Indian Defence GK** revision.
