Answer: Option D — 15,106 km
Detailed Solution
India has a land frontier of about 15,106.7 km, shared with seven neighbouring countries.
Breakdown of India's land borders (approximate):
- Bangladesh: 4,096.7 km.
- China: 3,488 km.
- Pakistan: 3,323 km.
- Nepal: 1,751 km.
- Myanmar: 1,643 km.
- Bhutan: 699 km.
- Afghanistan: 106 km.
- Total: about 15,106.7 km.
Coastline:
India's coastline, including the Andaman and Nicobar Islands and Lakshadweep, was traditionally measured as about 7,516.6 km.
A new measurement released in 2025, using modern mapping methods, gives the coastline as about 11,098 km. The difference is due to better measurement of irregular coastlines and islands, not physical change.
Gujarat has the longest coastline among the states.
States and UTs with land borders:
Sixteen states and two Union Territories (Jammu and Kashmir and Ladakh) share land borders with other countries.
Some states border more than one country:
- West Bengal: Bangladesh, Nepal and Bhutan.
- Arunachal Pradesh: China, Bhutan and Myanmar.
- Mizoram: Bangladesh and Myanmar.
Border management:
- The Department of Border Management, under the Ministry of Home Affairs, is responsible for managing India's land and coastal borders.
- Integrated Check Posts (ICPs) have been set up at major land crossings, such as Attari (Punjab), Petrapole (West Bengal), Agartala (Tripura) and Raxaul (Bihar), under the Land Ports Authority of India.
- The Vibrant Villages Programme, launched in 2023, aims to develop villages along the northern border.
Challenges:
- India's borders pass through very diverse and difficult terrain, from glaciers and high mountains to deserts, marshes, rivers and dense forests.
- Problems include infiltration, smuggling, illegal migration and disputes over undefined boundaries.
Why not the other options?
- ✗7,516 km is the traditional figure for India's coastline, not its land border.
- ✗10,200 km and 22,500 km are incorrect.
Quick tip
Remember: India's land border = about 15,106.7 km with 7 countries (longest Bangladesh, shortest Afghanistan); traditional coastline = 7,516.6 km.
