Answer 2

Cell mediated immunity is directly responsible for all except antibody production

Explanation:

Cell mediate immunity does't involve production of antibody but they activates phagocytes,antigen specific cytotoxic T lymphocytes,cytokines that are responsible for killing antigens.

Adaptive immune system are of 2 types- humoral and cell mediate immunity.

The humoral immune system helps in production of antibody that kills the antigen or foreign microbes.

Humoral immune system is rapid where as cell mediate immune response has slow effect by killing the microbes.
