Answer to Question 1

C
Feedback:
The third stage of inflammation involves opsonization, which facilitates phagocytosis. During opsonization, a substance coats the foreign antigens, producing inflammation. This inflammation makes the antigens more susceptible to the macrophages and leukocytes, thus increasing phagocytic activity. Opsonization is not characterized by T-cell activity or changes in blood flow and viscosity.

Answer to Question 2

C
