Billy cannot produce the antibody for the Rh factor, which means he is Rh-negative. Therefore, he cannot receive Rh-positive blood, which eliminates options A, B, and D. However, he can receive Rh-negative blood, so option E (O-) can be given safely to Billy. The remaining option, B(-), cannot be given safely to Billy because he would produce antibodies against the B antigens.
