Which of the following types of cells is primarily responsible for the destruction of old cells and invasive micro-organisms?

  • A. Basophils
  • B. Eosinophils
  • C. B-cells
  • D. Macrophages
Correct Answer: D

Rationale: Macrophages are a type of white blood cell that plays a crucial role in the immune system by engulfing and digesting cellular debris, foreign substances, microbes, cancer cells, and old or damaged cells. Basophils are primarily involved in allergic reactions and parasitic infections, eosinophils combat multicellular parasites and have a role in allergic reactions, and B-cells are responsible for producing antibodies. Therefore, the correct answer is macrophages as they are specialized in phagocytosis and removal of unwanted cells and microorganisms.
