"Langerhans cells transport harmful substances to white blood cells."

Brief explanation: Langerhans cells are antigen-presenting dendritic cells in the skin that capture pathogens/antigens and carry them to lymphoid tissue to activate T cells and other immune responses. The other choices describe reflexes or incorrect roles (pupil constriction is a nervous reflex, shivering is thermoregulation, and B cells don't adjust blood pH).
