Which immune cell stays after an infection is gone in order to produce antibodies?
Memory T cell
Memory B Cell
Natural killer cell
Mast cell
The Correct Answer is B
A. Memory T cell: Memory T cells are important for the adaptive immune response and provide cellular immunity but are not responsible for producing antibodies.
B. Memory B Cell: Memory B cells remain in the body after an infection has been cleared and are responsible for producing specific antibodies upon re-exposure to the same pathogen.
C. Natural killer cell: Natural killer cells are part of the innate immune system and function to kill virally infected cells and tumors but do not produce antibodies or have memory capabilities.
D. Mast cell: Mast cells are involved in allergic reactions and defense against parasites but do not produce antibodies and are not part of the memory response.

Correct Answer is D
Explanation
A. Bacteria: Interferons are not primarily effective against bacteria; they are specific to viral infections.
B. Parasites: While some immune responses can involve interferons, they are not specifically targeted against parasites.
C. Fungi: Interferons have limited activity against fungal infections, making them less effective compared to their antiviral properties.
D. Viruses: Interferons are proteins produced by virus-infected cells that help to protect neighboring cells from viral infection by enhancing the immune response and inhibiting viral replication.
