   Neyyar, Peppara and

   (a) Neyyar, Peppara and Shendurney Wildlife Sanctuaries, with Kalakad–Mundanthurai Tiger Reserve. These Kerala–Tamil Nadu units lie in the Agasthyamalai (Agasthyamala) Biosphere Reserve in the southern Western Ghats. That set is the official key.

   (b) Mudumalai, Sathyamangalam, Wayanad and Silent Valley. These belong to the Nilgiri Biosphere Reserve cluster, not Agasthyamala, so this is not the key.

3. C

   Kaundinya, Gundla Brahmeswaram and Papikonda wildlife Sanctuaries; and Mukurthi National Park

   (c) Kaundinya, Gundla Brahmeswaram, Papikonda and Mukurthi. These are Eastern Ghats / Andhra and Nilgiri names mixed; they are not the Agasthyamala set, so this is not the key.

   Kawal and Sri Venkateswara Wildlife Sanctuaries; and Nagarjunasagar-Srisailam Tiger Reserve

   (d) Kawal, Sri Venkateswara and Nagarjunasagar–Srisailam. Telangana–Andhra tiger and sanctuary landscape, not Agasthyamala, so this is not the key.
