• B. Oxygen transport in the blood
• C. Clotting of blood
• D. Defence mechanisms of body

Answer 1

Answer: (D)

Defence mechanisms of body

Immunoglobulins are the proteins which are present in the blood plasma. These are mainly involved in the blood plasma. These are released in response to the antigens and are known as antibodies. These are Y shaped proteins. The antigen binding site on the antibody is known as paratope. The process by which the antibody recognizes an antigen and gets attached is known as agglutination. It is composed of two large heavy chains and two small light chains.

So, the correct answer is option D.
