D Correct answer
Explanation

Historically immune system was differentiated into two groups: humoral immunity where protective purpose of immunisation could be present in humor (cell free serum) and cellular immunity where protective purpose of immunisation was correlated with cells. CD4 cells or helper T cells protects against several pathogens. Due to death of cytotoxic T cells by apoptosis without the use of cytokines in the cell mediated immunity, presence of cytokines is optional.
