Answer

Answer:

A. Fever increases red blood cell production.

Brief Explanations:

Fever is a sign of the immune - system response. It can increase red - blood - cell production as part of the body's defense mechanism against pathogens. The other options are not the main ways fever indicates immune system activity. For example, while fever can be associated with inflammation, it is not the primary way it shows the immune system is working. And fever is not mainly about triggering the body's temperature to directly destroy harmful substances or causing hormone secretion to fight them.
