Solution
The correct option is A Physiological barriers
Saliva in the mouth and the tears from the eyes belong to physiological barriers under innate immunity.
Physical Barriers of the innate immune system includes skin, the gastrointestinal tract, the respiratory tract, the nasopharynx, cilia, eyelashes and other body hair.
Cytokine barriers play a main role in the innate immune response by means of direct mechanisms against the invading agent (inhibiting viral replication) or by activating mechanisms for cells such as NK cells and macrophages, which upon activation, produce more cytokines.
