Final answer:
Cell-mediated immunity involves T lymphocytes which are responsible for destroying cells infected with intracellular pathogens like viruses and some cancer cells.
Step-by-step explanation:
Cell-mediated immunity is an adaptive immune response that is primarily orchestrated by T cells. This type of immunity leads to the destruction of cells that are infected with viruses and some cancer cells. The various T cells involved in cell-mediated immune responses include helper, cytotoxic, and regulatory T cells. Therefore, cell-mediated immunity generates A) T lymphocytes.
