a. The girl most likely has something wrong with her brain, because it should be at least 10% larger than the boy's brain.
b. The girl's brain most likely has something wrong with it, because it should be very close to the same size as the boy's brain at this age.
c. The girl most likely was malnourished in early childhood, giving rise to a smaller-than-average brain.
d. There is no reason for concern, since children's brain sizes can vary by as much as 50% without any appreciable difference in cognitive skills.
