The correct answer is C.
Blood is considered to be a dangerous body fluid. Infections, diseases, viruses and bacteria can all be found in blood. If one person has 'bad' blood they can pass on what is contained in their blood to another person. This can happen in a variety of different ways which is why healthcare professionals have strict regulations and guidelines when dealing with blood as they risk exposure to many types of infection or illness from patients. It can be dangerous for anyone to come into contact with blood from another person especially if there is a means of transmission from them to you for example if you have an open sore or wound on your body that could become exposed to their blood or through sharing intravenous drugs.
