The cheetah’s body is built for speed, allowing it to run at incredible speeds to catch prey. It has a lightweight, flexible frame with long, powerful legs that help it sprint. Its large nasal passages allow for increased oxygen intake, supporting its speed. Its body is adapted to regulate its temperature during intense running. Cheetahs also have specialised pads on their feet that reduce friction, enabling them to maintain grip on the ground while running.

Read the following text and answer the question:
The Arctic fox is well adapted to survive in cold environments. It has a thick coat of fur that provides insulation against the freezing temperatures. During the winter months, the Arctic fox grows an even thicker coat, and its fur changes color to blend in with the snow, helping it to camouflage. Additionally, the Arctic fox uses its hearing to locate prey beneath the snow and digs in the snow to catch small animals like lemmings.
Which of the following is the best example of a behavioral adaptation described in the text?
The Arctic fox’s thick coat of fur for insulation.
The Arctic fox’s fur changing color to blend in with the snow.
The Arctic fox using its keen sense of hearing to locate prey beneath the snow.
The Arctic fox’s sharp claws for digging into the snow.
