Correct answer

Thrombocytopaenic purpura is a type II hypersensitivity (or cytotoxic-type hypersensitivity) in which autoantibodies have been formed against thrombocytes.These autoantibodies may arise from the use of vaccines that contain blood products or in multiparous sows that develop antibody against the alloantigens shared by the sire and the foetus.
