Which 1988 operation involved Indian forces responding to an attempted coup in the Maldives?

Correct Answer: Option C — **Operation Cactus**. **Operation Cactus** is the accurate answer because Operation Cactus rapidly deployed Indian forces to assist the Maldivian government during the coup attempt. This identifying fact establishes its correct connection with overseas military operation and distinguishes it from the other defence-related choices. Why the other options are incorrect: Option A — **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. Option B — **1958**: This is actually associated with organisation history; specifically, DRDO was formed in 1958 by combining existing defence science and technical organisations. Option D — **Surface-to-surface ballistic missile**: This is actually associated with ballistic missile; specifically, Prithvi was developed as an Indian surface-to-surface ballistic missile series. Exam Takeaway: Link **Operation Cactus** with its exact **overseas military operation** association for fast **Indian Defence GK** revision.
