John,a Peace Corps worker in the country of Mali in Africa,was in a car accident while traveling through a rural area.He was treated at a tiny rural hospital,and due to his loss of blood required a transfusion.John is B- blood type and has never received a transfusion before.Which statement is correct regarding this scenario?

A) He can safely receive O- blood even though he makes anti-A antibodies.
B) He can be give types O or B,no matter whether Rh- or Rh+.At this point in time,he does not have anti-Rh antibody.O has no antigens on the blood cells,so he is also safe to receive that type in addition to his own B type.
C) He can be given A+ blood type,in addition to B+.Rh- means that he makes no antibody to Rh.
D) The preferred blood type to give John,in addition to his own B type blood,would be AB.Both types of blood have the B antigen on the cells,so they would correspond to his own antigens.As for Rh,he can receive only Rh- blood since he would have a reaction against Rh+.
