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, he required a transfusion. John has B- blood type and has never received a transfusion before. Which statement is correct regarding this scenario?
A. He can be given 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.
B. 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+.
C. He can safely receive O- blood even though he makes anti-A antibodies.
D. He can be given A+ blood type in addition to B+. Rh- means that he makes no antibody to Rh.
