A-III, B-IV, C-II, D-I
Solution
A. B-Lymphocytes: B-lymphocytes are a type of white blood cell that produce antibodies, which are proteins that recognize and neutralize pathogens. They are responsible for humoral immunity and produce an army of proteins (antibodies) in response to pathogens. Thus, A-III.
B. Interferons: Interferons are a group of signaling proteins produced and released by host cells in response to the presence of several pathogens, such as viruses, bacteria, parasites, and also tumor cells. They are part of the innate immune system. Thus, B-IV.
C. T-Lymphocytes: T-lymphocytes, or T cells, are a type of white blood cell that play a central role in cell-mediated immunity. They directly attack infected cells or help activate other immune cells. Thus, C-II.
D. Colostrum: Colostrum is the first milk produced by mammals after giving birth. It’s rich in antibodies that provide passive immunity to newborns. Thus, D-I.
