Consider the following fauna: 1. Lion-tailed Macaque 2. Malabar Civet 3. Sambar Deer How many of the above are generally nocturnal or most active after sunset?

Here's an analysis of the nocturnal activity of the listed fauna:

1. Lion-tailed Macaque: This primate is diurnal, meaning it is primarily active during daylight hours. They inhabit the upper canopy of tropical rainforests. Hence, statement 1 is not correct.

2. Malabar Civet: The Malabar Civet is nocturnal. Due to its elusive nature, detailed information about its ecology is limited. Hence, statement 2 is correct.

3. Sambar Deer: Sambar deer exhibit crepuscular (active at dawn and dusk) or nocturnal behavior. This means they are generally active around sunset and sunrise or during the night. Hence, statement 3 is correct.

Therefore, only two of the listed fauna (Malabar Civet and Sambar Deer) are generally nocturnal or most active after sunset.
