The correct answer is: C.Immune cell signaling.

Explanation:

Immune cell signaling involves the use of chemical signals (such as cytokines and other signaling molecules) to detect and respond to pathogens. When immune cells recognize pathogens (such as bacteria or viruses), they release chemical signals that initiate an immune response, help activate other immune cells, and coordinate the defense against infections. This process is crucial for the body's ability to detect and fight off infections.

The other options are incorrect because:
