Which one of the following protected areas is well-known for the conservation of a sub-species of the Indian swamp deer (Barasingha) that thrives well on hard ground and is exclusively graminivorous ?

Kanha National Park is the only natural habitat of the "Hard-ground Barasingha" (*Rucervus duvaucelii branderi*), a sub-species that uniquely adapted to the hard alluvial grasslands of Central India and is strictly graminivorous. While Manas National Park also conserves swamp deer, it hosts the Eastern sub-species which thrives in wet, marshy riverine habitats rather than the hard-ground environment specified. The core concept tested is the specific ecological niche and geographical distribution of endangered fauna within India’s protected area network.
