D Correct answer
Explanation

American crocodiles do have several remarkable adaptations: they can close their nasal passages underwater, they continually replace their teeth throughout life, and some birds do clean their teeth. However, their average lifespan is 70-100 years in the wild, not exactly 'an average of 100 years,' making this the least accurate statement.
