A.

?Yes, it does make sense to use the difference between each IQ score and brain volume in the same? column, because high IQ is caused by large brain volume.

B.

?Yes, it does make sense to use the difference between each IQ score and brain volume in the same? column, because they are measurements obtained from the same person.

C.

?No, it does not make sense to use the difference between each IQ score and brain volume in the same? column, because IQ scores and brain volumes use different units of measurement.

D.

?No, it does not make sense to use the difference between each IQ score and brain volume in the same? column, because the terms should be added.

E.
