Solution

The correct option is A
B lymphocytes only
B cells, otherwise called B lymphocytes, are a sort of white platelet of the lymphocyte subtype. They work in the humoral insusceptibility segment of the versatile, safe framework by emitting antibodies.

B lymphocytes comprise 1 to 10% of the lung lymphocyte population and can be separated into two main classes. Plasma cells constitutively secrete IgG and other immunoglobulins.

The humoral immune system deals with antigens from pathogens that are freely circulating, or outside the infected cells. Antibodies produced by the B cells will bind to antigens, neutralizing them, or causing lysis (dissolution or destruction of cells by a lysin) or phagocytosis.
