Which of the blood components in the diagram would proliferate during a viral infection? A B C D

B

Explanation:

I believe letter B is a "monocyte."

A monocyte is a large white blood cell (the largest leukocyte) that functions in the body's immune response. They are produced in the bone marrow and are then released into the blood stream. Once they reach the tissues in the body, they are then called "macrophages."

A high level of monocyte in the body signals that the body is fending off something. This can be a result of viral infections, parasitic infections, tuberculosis, parasitic inflammatory disease, cancer, etc. The proliferation of monocytes in the blood is called "monocytosis." This activates the person's immune response.

Prolonged monocytosis has the tendency to damage tissues since the inflammation has a hard time subsiding.

Thus, this explains the answer.
