1) Option 'e' is the correct answer.
O- blood type lacks any kind of antigen. It has antibodies in plasma for both anti-A and anti-B as well as Rh antibodies. If there are no antigens at all on the surface of the red blood cells, all three possible antibodies are present in the blood plasma: A, B and Rh antibodies.
2) Option 'd' is the correct answer.
Thymus gland lies in the mediastinum posterior to the sternum and between the lungs. It is most prominent in infants, becoming smaller in size through adulthood. The thymus produces hormones referred to as thymosins, which contribute to the development of the immune response.
3) Option 'e' is the correct answer.
Submandibular nodes are responsible for serving/drainage of mandible bone. There are usually between 3-6 submandibular nodes. They are located below the mandible in the submandibular triangle and collect lymph from the cheeks, the lateral aspects of the nose, upper lip, lateral parts of the lower lip, gums and the anterior tongue. They also receive lymph from the submental and facial lymph nodes.
4) Option 'b' is the correct answer.
Type A+ person will have B antibodies in his blood and A as well as Rh antigens
