Explanation / Answer

1). Interferons (IFNs) are signaling proteins released by host cells in response to the presence of several pathogens, such as viruses, bacteria, parasites, and also tumor cells

So option, C interferons

2). Siderophores are amongst the strongest soluble Fe3+ binding agents.

So option, B Siderophores

3). produced by plasma cells that is used to neutralize pathogens such as bacteria and viruses

So option,A Antibodies

4). They are produced by white blood cells known asB cells.

So option, E B-cells
