Explanation:

Question 108

Interferons are proteins released by cells in response to viral infections. They act to inhibit the replication and spread of viruses. Bacteria are typically combated by antibiotics or other immune responses like phagocytosis, not interferons. B - cell antibodies are part of the adaptive immune response and not inhibited by interferons. So interferon inhibits the spread of viruses.

Lymph nodes are part of the lymphatic system and are involved in the production and maturation of lymphocytes (a type of white blood cell). Among the options, monocytes are a type of white blood cell that can be produced or matured in lymph nodes. Eosinophils, erythrocytes (red blood cells), and neutrophils have different production sites (e.g., erythrocytes are produced in bone marrow, eosinophils and neutrophils are also mainly produced in bone marrow).

Answer:

A. viruses.
