E

Bill wants to determine his blood type, so he takes a few drops of blood from a puncture wound in his finger and mixes it with various antisera. His blood cells agglutinate when mixed with the anti-A serum and anti-Rh serum, but not with the anti-B serum. This means A) Bill could receive type B blood in a transfusion.
