Why can't a person with type B blood (recipient) receive a bloodtransfusion from someone with type A blood (donor)?

the recipient's anti-B antibodies will react with the donated Bantigens

the recipient's anti-A antibodies will bind to the A antigensof the donated blood cells

the recipient's anti-A and anti-B antibodies will react withthe donated blood cells

the recipient's anti-O antibodies will bind to the O antigen ofthe donated blood cells

no reaction would occur because the B-type individual does nothave antibodies
