Official UPSC Answer KeyUPSC Prelims 2023 • Environment and Ecology

Correct Answer: Option (A) — Only one

Concept & Option Breakdown

Standard Reference Verified
  1. Lion-tailed Macaque is diurnal, active primarily in the upper canopy during daytime.
  2. Malabar Civet is strictly nocturnal and highly elusive.
  3. Sambar Deer is predominantly crepuscular (active at dawn and dusk) rather than strictly nocturnal. Therefore, only one (Malabar Civet) fits the description of being generally nocturnal.
