Correct answer: "B cells produce antibodies, and T cells destroy infected cells."

Brief explanation:
- B cells develop in the bone marrow and differentiate into plasma cells that secrete antibodies to neutralize pathogens and help opsonize them for phagocytosis.
- T cells develop in the thymus (after originating from bone-marrow progenitors). Cytotoxic (CD8+) T cells kill virus-infected or otherwise abnormal cells; helper (CD4+) T cells coordinate immune responses; regulatory T cells suppress them.
- The other choices are incorrect: B cells do not regulate blood pH, nor are they primarily phagocytes; T cells do not regulate body temperature and are not produced in bone marrow (they mature in the thymus).
