RAS question
The Sundarbans is shared between India and:
Correct answer: (B) Bangladesh.
The Sundarbans is shared between India and Bangladesh.
Explanation
The Sundarbans is not an India-only ecosystem; it lies across India and Bangladesh. Its spread is about 10,000 sq km, with roughly 40% in West Bengal, India, and roughly 60% in Bangladesh. UNESCO describes the Sundarbans as straddling the Ganges and Brahmaputra deltas between India and Bangladesh, and identifies it as the world's largest mangrove forest. That is why Bangladesh is the required answer. The other labels may be South Asian or coastal countries in different contexts, but they do not share the Sundarbans.
Why the other options are wrong
- (A) Myanmar has mangrove ecosystems of its own, but the Sundarbans lies between India and Bangladesh, not Myanmar.
- (C) Sri Lanka is not part of the Ganges-Brahmaputra delta setting identified by UNESCO and does not share the Sundarbans with India.
- (D) Nepal is landlocked, so it cannot be the country sharing this deltaic mangrove forest with India.
Concept
This tests the Environment and Ecology habit of linking famous ecosystems with their political geography. RAS repeats such locations because protected areas, Ramsar sites, World Heritage sites and tiger habitats are often asked through map-based facts.
