The only anthropoid ape to be found in India is the

Answer: (d) white browed gibbon of Assam

The hoolock (white-browed) gibbon of the North-East is India’s only ape.

The idea

“Anthropoid” means man-like. The hoolock gibbon is the only ape that reaches India, living in the tall forests of the North-East south of the Brahmaputra. The other three options are two monkeys and a loris.

Hanuman monkey: a langur, has a tail → Lion-tailed macaque: a monkey, has a tail → Slow loris: an early primate → Hoolock gibbon: no tail, long arms → ape

Why the others are wrong

(a) The Hanuman langur is a monkey.

(b) The lion-tailed macaque is a monkey.

(c) The slow loris is a prosimian, not an ape.

Also know

The male is black with white eyebrows and the female is light brown. A family sings loudly together each morning. Gibbons hardly ever come down, so even one road or railway line through the forest can divide a group.
