ANATOMY

Detailed explanation-1: -No. Cytotoxic T-cells play a role in cell-mediated immunity, a type of adaptive immunity. Innate immunity is the immunity already present in your body. You develop adaptive immunity when you’re exposed to infections or other foreign substances.

Detailed explanation-2: -Cell-mediated immunity, unlike humoral immunity, does not rely on antibodies to perform adaptive immunological activities. Mature T cells, macrophages, and the production of cytokines in response to an antigen are the main drivers of cell-mediated immunity.

Detailed explanation-3: -B-lymphocytes form army of proteins called antibodies in response to pathogen in blood and are stimulated by antigen and T-helper cells. Therefore, B-lymphocytes provide humoral mediated immunity. T-lymphocytes provide cell mediated immunity. So, the correct option is ‘B-lymphocytes’.
