C. Monocyte: Monocytes are large white blood cells that develop into macrophages but do not include B or T cells.

Explanation
A. Bone marrow: The bone marrow is primarily responsible for the production of blood cells, including red blood cells, rather than their removal.
B. Tonsils: The tonsils are part of the immune system and help filter pathogens but are not primarily involved in removing old red blood cells.
C. Thymus: The thymus is involved in the maturation of T-lymphocytes (T-cells) and does not have a role in filtering blood or removing red blood cells.
D. Spleen: The spleen filters the blood, removes old and damaged red blood cells, and helps in the immune response by filtering pathogens.
Correct Answer is D
Explanation
A. Fully mature and leave the epididymis: The acrosome does not play a role in sperm maturation or their release from the epididymis.
B. Travel through the male reproductive ducts: Movement through the reproductive ducts relies on the sperm's flagellum and muscle contractions, not the acrosome.
C. Develop a full set of chromosomes: Chromosome development occurs during spermatogenesis and is unrelated to the acrosome.
D. Breach and fertilize the ovum: The acrosome contains enzymes that allow the sperm to penetrate the ovum during fertilization. Without an acrosome, the sperm would be unable to breach the egg’s outer layer.
