Biosphere Reserves and Protected Areas

Examining each pair: Pair 1 - Nokrek Biosphere Reserve is in the Garo Hills of Meghalaya, so this appears correct. Pair 2 - Loktak Lake is in Manipur, but the Barail Range is not the correct geographical feature; Loktak is in the Manipur Valley and the nearby hills are the Manipur Hills, not specifically Barail Range. The Barail Range is in Manipur and Nagaland but not directly associated with Loktak Lake. Pair 3 - Namdapha National Park is in Arunachal Pradesh, located in the Patkai Range, not the Dafla Hills. The Dafla Hills refer to the Dafla tribe area, but the park is primarily in the Patkai/eastern ranges. All three pairs have geographical mismatches. Therefore, none of the pairs is/are correctly matched.
