Correct Answer: Option (C) — Langur

Concept & Option Breakdown

Standard Reference Verified
  • Langurs are Old World monkeys belonging to the family Cercopithecidae (subfamily Colobinae). They possess prominent tails used for balance in arboreal locomotion.
  • Gibbons are 'lesser apes' (Family Hylobatidae).
  • Gorillas and Orangutans are 'great apes' (Family Hominidae).
  • A key anatomical feature distinguishing all apes from monkeys is that apes lack an external tail.
Elimination Heuristic & Exam Approach

Apes do not have tails (Gibbon, Gorilla, Chimpanzee, Orangutan, Bonobo). Langurs have prominent tails, making them monkeys.
