Detailed explanation-1: -Group C blood is different in that it agglutinates with both A and B. This was the discovery of blood groups for which Landsteiner was awarded the Nobel Prize in Physiology or Medicine in 1930. (C was later renamed to O after the German Ohne, meaning without, or zero, or null.)
Detailed explanation-2: -Option: C – As per the ABO blood group system a person can have ‘A, B, AB or O’ blood group and can be either Rh positive or negative. So, a person cannot have ‘BC blood type. So, Option C is correct as BC is not a recognized blood group.
Detailed explanation-3: -A blood type (also called a blood group) is defined as the classification of blood based on the presence or absence of inherited antigenic substances on the surface of red blood cells (RBCs). A series of related blood types constitutes a blood group system, such as the Rh or ABO system.
Detailed explanation-4: -There are 4 main blood groups (types of blood) – A, B, AB and O. Your blood group is determined by the genes you inherit from your parents. Each group can be either RhD positive or RhD negative, which means in total there are 8 blood groups.
