Below are two statements about the immune system: macrophages ingest and degrade microbes and present the microbial antigens to other immune system cells. antibodies on the surface of virally infected host cells activate natural killer (nk) cells. these two statements are examples of the connections between which of the following? choose one: a. neutrophil extracellular traps (nets) and the disease lupusb. phagocytosis and inflammationc. primary and secondary lymphoid tissuesd. innate and adaptive branches of immunity.

D. innate and adaptive branches of immunity.

Explanation:

macrophages function is the phagocytosis of the microbes which is an innate response from immune system. The phagocytosed degraded microbes will then initiate the adaptive response.

Presentation of the degraded microbial antigens activates the adaptive response. Antibodies of the adaptive immunity on the surface of virally infected host cells activate natural killer (NK) cells.
