Answer: (D)

The nasion is the anatomical landmark that is specifically defined as the indentation between the nose and the forehead. It represents the junction of the frontal and nasal bones on the human skull, forming a distinct feature that can easily be palpated. The nasion is significant in various medical and anatomical contexts, as it serves as a reliable reference point for positioning and measurements in areas like craniofacial surgeries and imaging studies. Recognizing this landmark helps healthcare providers accurately identify locations for procedures or assessments involving the facial structure.
