Answer #1

The main difference between systemic and mucosal immunity is d) no T cells are involved in mucosal immunity because if A play an important role in this immunity but in case of systemic immunity, T cells as well as antibody secreting B cells.

Other options are not correct because they are not characterized by low inflammation.
