C.AB,Rh-

According to ABO system of blood groping, O type blood can be given to person of all types of blood, i.e., O, A, B and AB. Hence, a person with O type blood is called universal donor.According to Rh system of blood grouping, most of the people have blood in which there is a sub stance called Rh factor. Rh stands for rhesus. This type of blood can be donated only in rarest of rare chances. in india about 97% of people are, Rh-. So, if an Rh+ person is transfused with, Rh+ blood then it is safe. But if an Rh negative (,Rh-) person is transfused with, Rh- blood then he/she will develop anti-Rh fector i.e., antibodies in his/her blood and no harm is done.
