Final answer:
The correct relationship in pathogen recognition is that PRRs on macrophages recognize PAMPs on pathogens. This interaction triggers the immune response, leading to the elimination of the pathogen.
Step-by-step explanation:
The correct relationship between components of the innate immune system involved in pathogen recognition is: PRRs on macrophages recognize PAMPs on pathogens. Pattern recognition receptors (PRRs) are molecules on cells such as macrophages and dendritic cells, which are designed to recognize pathogen-associated molecular patterns (PAMPs) that are features inherent to pathogens but not present on host cells. The interaction between PRRs on immune cells and PAMPs on pathogens leads to the activation of the immune response, including the engulfment and destruction of the invading pathogens.
