On Examination of the Abdomen of a 31-Year-Old Woman, a Large

On examination of the abdomen of a 31-year-old woman, a large swelling was found to extend downward and medially below the left costal margin. On percussion, a continuous band of dullness was noted to extend upward from the left of the umbilicus to the left axillary region. On palpation, a notch was felt along the anterior border of the swelling. A diagnosis of splenic enlargement was made.
-The signs displayed by this patient can be explained by the following statements except which?

A) The spleen has a notched anterior border caused by incomplete fusion of its parts during development.
B) Because of the presence of the left colic flexure and the phrenicocolic ligament, the spleen is unable to expand vertically downward.
C) A pathologically enlarged spleen extends downward and forward, toward the umbilicus.
D) The spleen is situated in the upper left quadrant of the abdomen beneath the diaphragm.
E) The long axis of the spleen lies along the twelfth rib.
