What is the primary function of the natural killer cell?
Producing early induced proteins
Promoting opsonization of bacteria cells
Secreting signaling molecules
Destroying virally infected cells
The Correct Answer is D
A. Producing early induced proteins: While natural killer cells can produce cytokines, their primary function is not related to protein production.
B. Promoting opsonization of bacteria cells: Opsonization is primarily performed by antibodies and complement proteins, rather than natural killer cells.
C. Secreting signaling molecules: While natural killer cells do secrete signaling molecules (cytokines) to communicate with other immune cells, their main role is the direct destruction of infected cells.
D. Destroying virally infected cells: The primary function of natural killer cells is to recognize and eliminate virally infected cells and tumor cells, contributing to the innate immune response.

Correct Answer is D
Explanation
A. Dendritic cells: Dendritic cells are antigen-presenting cells that originate from precursor cells in the bone marrow, but they do not differentiate from monocytes.
B. Bacterial cells: Bacterial cells are pathogens and do not differentiate into any immune cells.
C. Natural killer cells: Natural killer cells are a type of lymphocyte involved in the innate immune response but do not differentiate from monocytes.
D. Monocyte cells: Monocytes are a type of white blood cell that, upon migrating into tissues, differentiate into macrophages, which play a key role in phagocytosis and immune response.
Correct Answer is D
Explanation
A. Eosinophil: Eosinophils are involved in allergic reactions and parasitic infections, but they are not responsible for B and T cell functions.
B. Basophil: Basophils are involved in inflammatory responses, particularly releasing histamine, but do not include B or T cells.
C. Monocyte: Monocytes are large white blood cells that develop into macrophages but do not include B or T cells.
D. Lymphocyte: Lymphocytes are a subtype of white blood cells that include B cells (which produce antibodies) and T cells (which are involved in cell-mediated immunity), making this the correct answer.
