Solution
The correct option is D Antibody will form
Correct option : (d) Antibody will form
(d) The Rh+ve blood cells can be destroyed by an anti Rh+ve antibody of the Rh-ve person. The immune system of the Rh-ve person will recognize the Rh+ve blood cells as foreign and will produce antibodies against them.
Incorrect Options:
(a) In this option, no antigen formation takes place, as RBCs do not have any antigen receptors. Thus, Rh-ve blood cannot be sensitized by exposure to Rh+ve RH antigens.
(b) Rh-ve person is exposed to the blood from a Rh+ve person, where -ve and +ve Rh antigen cancel out each other.
(c) There will be a process that occurs, like antibodies so changes occur.
