what type of antibodies are present in plasma for type a blood?
anti - o antibodies
anti - d antibodies
anti - a antibodies
anti - b antibodies
anti - rh antibodies

Explanation:

Blood type A has A antigens on red blood cells. Plasma contains antibodies against antigens not present on its own red blood cells. Since type A doesn't have B antigens, it has anti - B antibodies. Anti - O antibodies don't exist as O is a base type without specific antigens in this context. Anti - D and anti - Rh are related to Rh factor (not the ABO system). Anti - A antibodies would attack its own cells (not normal).

Answer:

anti - B antibodies
