2. Active during twilight hours

3. Sleep all day

4. Active throughout the night

The correct answer is: Active during twilight hours

Crepuscular animals are known for being most active during the twilight hours, which occur at dawn and dusk. This behavior is often an adaptation to avoid predators and take advantage of the cooler temperatures and lower light levels during these times. Animals with crepuscular habits, such as deer, rabbits, and many species of birds, typically exhibit increased activity during these periods when visibility is not too bright but sufficient for hunting or foraging. This timing also allows them to evade some diurnal predators, as well as nocturnal ones, by being active during times when most of their threats are less vigilant.
