c. they are capable of interacting with several antigens
Explanation:
Antibodies, also called immunoglobulins (Ig), are protein structures found in blood plasma. They act against invading organisms in the body, such as bacteria and viruses. The main function of antibodies is the body's defense, which act directly against invading microorganisms (also called antigens) that can cause various infections and diseases. In this way they neutralize the toxins of extracellular parasites.
Antibodies are produced by B lymphocytes and have the ability to specifically combine with substances foreign to the body, inactivating them. Antigens are extremely specific, so we can say that for each of their types there is a type of antibody, complementary to that of the antigen. Thus, antibodies are not able to interact with various antigens, but only those with which they establish a specific relationship.
