a

Only one

b

Only two

Answer
c

All three

d

None

Explanation

The Malabar Civet and the Sambar Deer are primarily nocturnal or crepuscular, heavily foraging during the night or twilight to avoid heat and predators. Conversely, the Lion-tailed Macaque is strictly diurnal, actively foraging in the Western Ghats rainforest canopy during daylight hours.

Most primates (like macaques) are diurnal, while most civets and many large forest-dwelling ungulates (like the Sambar) exhibit strong nocturnal behaviors.

Answer: (b).
