A researcher discovers that a breed of rabbits have antibodies that can neutralize HIV. The researcher decides to extract the antibody concentrated plasma and deliver it to a patient with HIV. What would you likely expect to see?    a. The HIV patient will now have a fighting chance to eliminate HIV as the antibodies will not discriminate and bind to the same viral antigenic determinants.   b. The HIV patient will form antibodies against the rabbit serum antibodies.   c. The rabbit antibodies will opsonize the HIV antigenic determinants on the MHC II.   d. The rabbit antibodies will never work because HIV in humans are different than HIV in rabbits.
