My 5th grader got this question wrong on his homework. Can you spot the problem with this problem?

You are now halfway down [your Grand Canyon hike] and spot an endangered California Condor nesting about 63 meters from where you are. How many millimeters away is that?

A. 6300 cm
B. 63,000 cm
C. 73 cm
D. 630 cm

Am I missing something here?
