Cells involved in which type of immunity produce antibodies?

• A. Humoral immunity
• B. Passive immunity
• C. Innate immunity
• D. Cell-mediated immunity

Answer: (A)

Verified step by step guidance

1. Understand the types of immunity: Immunity can be broadly categorized into innate immunity (non-specific defense mechanisms), adaptive immunity (specific defense mechanisms), passive immunity (temporary immunity from external sources), and humoral immunity (antibody production).
2. Focus on humoral immunity: Humoral immunity is a type of adaptive immunity where B cells are activated to produce antibodies that target specific antigens.
3. Clarify the role of antibodies: Antibodies are proteins that bind to antigens (foreign substances) to neutralize or mark them for destruction by other immune cells.
4. Differentiate humoral immunity from cell-mediated immunity: Cell-mediated immunity involves T cells that directly attack infected or abnormal cells, whereas humoral immunity relies on B cells and antibodies to combat pathogens in bodily fluids.
5. Conclude that cells involved in humoral immunity (specifically B cells) are responsible for producing antibodies, making humoral immunity the correct answer to the question.
