EXPLANATION

In 2023–24, the Ministry of Home Affairs (MHA) of India released revised data regarding the length of the country’s coastline.

🧮 What changed?

  • The recalculated coastline length is now:

    ➡️ 11,098 km

  • This is a significant increase from the earlier figure of 7,516 km.

🧭 Why was it revised?

    • Creeks

    • Tidal waterlines

  • As a result, the coastline appears longer and more detailed.

    • Greater maritime boundary responsibilities

    • More areas for coastal security and disaster management

    • Expanded scope for marine trade, fishing, and tourism

    • More accurate planning and policy making

🔁 Old vs New Coastline Length:

Description Length (in km)
Old (traditional) 7,516 km
New (2023–24) 11,098 km

✔️ Final Answer: C) 11,098 km
