D) differential assessment.

The results are best described as a double dissociation, which is when damage to two different brain areas results in opposite selective deficits. In this case, damage to Area A results in loss of Function A but not Function B, while damage to Area B results in loss of Function B but not Function A. This pattern provides strong evidence that Functions A and B are dissociable and are controlled by different brain regions.
