To answer this question, you need to know about the anatomy and behavior of different animals.
Option A) Cat - This option is incorrect. Cats can stick their tongues out. In fact, cats have a specialized tongue that is covered in tiny, backward-facing barbs called papillae, which help them groom their fur.
Option B) Tiger - This option is incorrect. Tigers, like other big cats, can stick their tongues out. They use their tongues to lap up water, groom their fur, and clean meat off bones.
Option C) Crocodile - This option is correct. Crocodiles cannot stick their tongues out. Unlike most other reptiles, crocodiles have a membrane that holds their tongue in place on the roof of their mouth, preventing them from extending it outside of their mouths.
Option D) Snake - This option is incorrect. Snakes can stick their tongues out. Snakes have long, forked tongues that they use to sense their environment, gather chemical information, and locate prey.
The correct answer is C) Crocodile. Crocodiles cannot stick their tongues out due to the structure of their mouths.
