Explanation

The western hoolock gibbon, India's only ape, is listed as Endangered by the IUCN, and the Hollongapar Gibbon Sanctuary in Assam is known for it. Gibbons are specialised brachiators, swinging arm over arm through the canopy. Statement 3 is wrong: gibbons are small, slender lesser apes, nothing like the heavy build of gorillas.
