(C) Crepuscular
(D) Diurnal

Answer 1

Hint: There are many animals like bats, stray dogs, rats, which are active during dawn and dusk also known as the twilight period.The term used for these animals is derived from the twilight.

Complete step by step answer:
An animal active during dawn and dusk is called a Crepuscular animal.
Crepuscular animal. is distinguished from diurnal and nocturnal behavior, where an animal is active during the hours of daylight and of darkness, respectively. Some crepuscular animals can also be active by moonlight or during an overcast day. Matutinal animals are active only before sunrise, and vespertine only after sunset.

Crepuscular animals are those animals that are mostly active during the dark hours of the whole day.
Several different factors impact the time of day an animal is active. Predators hunt when their prey is out there, and prey attempts to avoid the days when their principal predators are at large. The temperature at midday could also be too high or in the dark too low. Some creatures may adjust their activities by looking at the local competition. Due to their crepuscular habit, a prey population increases, predators will have more food thus increasing their population, which in turn decreases the prey, then the predators decrease, increasing the prey, and so on. crepuscular prey can use this light at this period to easily spot and avoid predators.
So, the correct answer is ‘Crepuscular '.

Note: Many different terms are used for distinguishing different types of animals. They are:
Auroral species animals that remain active at dawn.
Vespertine: Species most active during dusk.
Crepuscular: Species most active during both dawn and dusk (or twilight).
Diurnal: Species are most active during the daytime .
