Consider the following pairs : 1. Nokrek Biosphere Reserve : Garo Hills 2. Logtak (Loktak) Lake : Barail Range 3. Namdapha National Park : Dafla Hills Which of the above pairs is/are correctly matched?

The Nokrek Biosphere Reserve is correctly matched with the Garo Hills in Meghalaya [5]. It is a biodiversity hotspot located in the West Garo Hills district [5]. Loktak Lake is situated in Manipur [6], whereas the Barail Range primarily spans across Assam, Nagaland, and Manipur, acting as a watershed between the Brahmaputra and Barak river systems [4]. Therefore, Loktak Lake is not part of the Barail Range. Namdapha National Park is located in the Changlang district of Arunachal Pradesh, situated in the Patkai-Bum hills of the Eastern Himalayas [2]. The Dafla Hills are located further west in Arunachal Pradesh, between the Aka and Miri Hills [2]. Consequently, only the first pair is correctly matched, making option 1 the correct choice.
