Solution

The correct option is B

decrease the concentration of iron in the blood.


The correct answer is Option B

Explanation of correct option:

A single event of fever and/or inflammation in a person appears to inhibit the reticuloendothelial system's release of iron from red blood cells, resulting in a drop in serum iron content and long-term stimulation of ferritin formation.

Explanation of incorrect option:

Option A:

Interferons are a family of signaling proteins that are produced and released by host cells in response to the presence of a variety of viruses. Fever does not reduce interferon production.

Option C:

Phagocyte is a kind of cell capable of ingesting and digesting foreign particles such as bacteria, carbon, dust, or dye. Fever does not decrease the activity of phagocytes.

Option D:

Fever increases the body temperature and increased body temperature does not allow the growth of bacteria.

Final answer: Fevers decrease the concentration of iron in the blood.
