The correct option is D Creutzfeldt-Jacob disease
Bovine spongiform encephalopathy (BSE) or mad cow disease is a fatal disease that strikes the nervous system of cattle. Creutzfeldt–Jakob disease (CJD) is a universally fatal brain disorder in humans. BSE and CJD are part of the prion diseases. A prion is a type of protein that can trigger normal proteins in the brain to fold abnormally. Prion diseases can affect both humans and animals. BSE is the prion disease in animals and CJD is the prion disease in humans. So BSE is equal to CJD. So, the correct answer is 'Creutzfeldt-Jacob disease'.
