The process provides immunity against antigens and pathogens in the body fluids is called humoral immunity .
Hence, option C is correct .
Humoral immunity is mediated by the complement proteins, antimicrobial peptides and antibodies etc. It is called humoral immunity because it is found in body fluids and humors.
The humoral immunity provides immunity against the antigens and pathogens that are circulating in the body fluids, such as the lymph and blood. The humoral immunity involves the B-cells and helper T cells. It is also known as the antibody-meditated response. The B-cells recognize the pathogens. When the B cells are activated with the help of the helper T cells, they proliferate and produce plasma cells containing the antibodies.
Hence, the answer is 'Option C - humoral immunity'.
