Correct answer
Explanation
Giraffes have exceptionally long tongues, typically around 18-21 inches, which they use for various purposes including grasping leaves and grooming themselves. The 21-inch length is well-documented in zoological studies. 20-inch and 24-inch are close but not accurate, while 25-inch exceeds the typical range.
