RAS question
Which state shares the longest international border with Bangladesh?
Correct answer: (C) West Bengal.
West Bengal shares the longest international border with Bangladesh, with about 2,216 km of the India-Bangladesh border.
Explanation
West Bengal alone accounts for about 2,216 km of India’s border with Bangladesh. The Industries & Commerce, Government of Assam page gives the total India-Bangladesh border as 4096.7 km and states that 2216.70 km is shared with West Bengal. By contrast, the four North-Eastern border states together account for 1880 km. Their individual totals are much smaller: Tripura has 856 km, Meghalaya 443 km, Mizoram 318 km, and Assam 263 km. State-wise border-length comparison therefore places West Bengal clearly first, ahead of every North-Eastern state on the Bangladesh border.
Why the other options are wrong
- (A) Meghalaya shares 443 km with Bangladesh, which is substantial but far below West Bengal’s roughly 2,216 km.
- (B) Assam shares 263 km of border with Bangladesh, so it is much shorter than West Bengal’s border.
- (D) Tripura has the longest Bangladesh border among these North-Eastern states at 856 km, but it still does not match West Bengal’s roughly 2,216 km.
Concept
Political geography of India includes international borders and state-wise boundary lengths. RAS geography often checks precise map-based facts rather than broad regional impressions.
