At which one of the following places is the monkey called Liontailed macaque naturally found ?

The Lion-tailed macaque (Macaca silenus) is a primate species endemic to the tropical rainforests of the Western Ghats in southern India. Its natural distribution is restricted to the states of Karnataka, Tamil Nadu, and Kerala. Specifically, it is a key faunal species in the Nilgiri Biosphere Reserve, which was India's first biosphere reserve established in 1986 [2]. While the species is also found in the Annamalai Hills (including the Annamalai Tiger Reserve/Sanctuary) [t1][t2], the Nilgiris is the most comprehensive geographical region listed that encompasses its primary habitat and is historically associated with its conservation status in standard ecological literature [2][t5]. The Shivaliks and Pachmarhi are outside its natural range, as the species is strictly confined to the evergreen forests of the Western Ghats [t2][t8]. Therefore, the Nilgiris represents the most accurate natural location among the given options.
