Are secreted by cells infected with viruses, alerting neighboring cells and protecting them from becoming infected.
a. complement system globulins
b. interferons
c. granzymes
d. interleukins

The correct answer will be option B (Interferons).

Explanation:

The innate immune response to viral infection begins with the recognition of pathogen which starts viral host response in organism.

After detection of viral infection cell produces type I interferon's, the protein molecule which interfere with the proliferation of viral cells.

Interferon's provide resistance to viral infection by :

1. Binding to IFN-α/β receptors which activate JAK/STAT pathway.

2. Production of enzymes which leads to the degradation of viral RNA.

3. Induction of ds-RNA-dependent kinase which inactivates the synthesis of proteins.

4. Binding to Natural killer cells which induces lytic activity, killing viral infected cells.

Thus, option B-interferon is the correct answer.

kelp are large brown algae that live in cool, relatively shallow waters close to the shore. they grow in dense groupings much like a forest on land. these underwater towers of kelp provide food and shelter for thousands of fish, invertebrates, and marine mammal species.
