Solution

The correct option is A

True


Cytokines are cell signalling molecules produced by cells of the immune system. Cytokines serve as ‘alarm systems’ and attract the attention of other cells that kill infected human cells. These other cells are some “special cells” of our immune system which get activated to fight off the pathogen or even kill the infected cells. They are macrophages, neutrophils, monocytes and natural killer cells.
