Solution
The correct option is A Antibody Antibodies (also called immunoglobulins) are large proteins. They are found in the blood or other body fluids of vertebrates. Antibodies are the key element in the adaptive immune system. The antibody recognizes a unique part of the foreign target called an antigen. It is used by the immune system to neutralize pathogens such as pathogenic bacteria and viruses. Antibody is produced by plasma cells. Antibodies can occur in two physical forms, a soluble form that is secreted from the cell to be free in the blood plasma, and a membrane-bound form that is attached to the surface of a B cell and is referred to as the B-cell receptor (BCR).
