43. A patient who has been bitten by a rattlesnake is given an injection of equine anti-rattlesnake venom. Ten days later, he still feels weak all over, has headaches, aches in his muscles and joints, and has black urine. Studies in the lab reveal proteinuria. Immunoglobulin levels in the serum are within the normal range, while serum C3 and C4 levels are lower. Which of the following pathological processes is more likely? (A) Anaphylactic Reaction (B) Delayed Hypersensitivity to horse protein (C) Formation of antigen-antibody complexes containing horse proteins and human immunoglobulin (D) Formsation of antigen-antibody complexes containing snake venom proteins and a horse antibody (E) Systemic reaction to snake venom
