The Great Sphinx is a huge statue in Egypt that has a lion' s body with a man' s head. The face of the Sphinx has long been claimed to be that of pharaoh Khafre, who lived around 2600 B. C. , but it cannot be: erosion patterns recently discovered on the lion' s legs can only have been caused by heavy rains, and the Sahara has not had heavy rains in over 10, 000 years. Which of the following, if true, most seriously weakens the argument?
A: Other erosion patterns that appear on the body of the Sphinx are of a sort that could be caused by wind and sand alone
B: The face of the Sphinx bears a resemblance to the faces on certain stylized statues dating from both before and after the reign of Khafre.
C: Other than the Sphinx, there are no surviving sculptures that have been claimed to portray the face of Khafre.
D: The face of the Sphinx is small relative to the rest of the head, indicating that the face may have been recarved long after the Sphinx was built.
