Let’s check the given statements and find if they are correct:Statement 1: Snake and crocodile are cold blooded animals. ----- Correct. Snakes and crocodiles are reptiles.

They regulate their body temperature by lying in the sun to warm up, or moving into the shade to cool down.Statement 2: Snake and crocodile breathe through moist skin mostly. ----- Incorrect. Snakes and crocodiles breathe through lungs. That is where the exchange of gases takes place.That means Statement 1 is correct but Statement 2 is incorrect.Hence, the right answer of Option C.The correct answer is C.
