Task: Class Definition Understanding (ontology: Sciences/Biology)

Which of the following definitions best describes 'antimicrobial humoral response'?

A. An immune response dependent upon secreted immunoglobulin. An example of this process is found in Mus musculus.
B. Any process involved in the activation of any of the steps of the the concept, which allows for the direct killing of microbes, the disposal of immune complexes, and the regulation of other immune processes; the initial steps of the concept involve one of three pathways, the classical pathway, the alternative pathway, and the lectin pathway, all of which lead to the terminal complement pathway.
C. Any process in which an organism stops, prevents, or reduces the frequency, rate or extent to which it enters into a second organism, where the two organisms are in a symbiotic interaction.
D. An immune response against microbes mediated through a body fluid. Examples of this process are seen in the the concept of Drosophila melanogaster and Mus musculus.

Answer: An immune response against microbes mediated through a body fluid. Examples of this process are seen in the the concept of Drosophila melanogaster and Mus musculus.
