T cells are involved in the adaptive immune response, which takes time to develop after exposure to a pathogen. Since the student did not develop symptoms, it is likely that her innate immune system was able to handle the pathogen without needing to activate the adaptive immune response, which includes T cells. The other options, mucus, lysozymes, phagocytes, and the nonspecific defense provided by her skin, are all part of the innate immune system and could have contributed to her resistance.
