Answer: C: antifertilizinExplanation:- Spermatozoa are the male reproductive cells, also known as sperm cells.- The surface layer of the cytoplasm in spermatozoa contains a chemical substance called antifertilizin.- Antifertilizin plays a crucial role in the fertilization process by interacting with fertilizin, a substance found on the surface of egg cells (ova).- The interaction between antifertilizin and fertilizin allows the sperm cell to bind to the egg cell, facilitating successful fertilization and the formation of a zygote.- Other substances mentioned in the options are not found on the surface layer of cytoplasm of spermatozoa: - Fertilizin: Found on the surface of egg cells, not sperm cells. - Agglutinin: A substance that causes particles to clump together, not specifically related to spermatozoa. - Hyaluronidase: An enzyme that breaks down hyaluronic acid, aiding sperm penetration through the egg's outer layers, but not found in the surface layer of spermatozoa's cytoplasm.

Understanding the Chemical Substance in Spermatozoa
Spermatozoa, or sperm cells, play a crucial role in reproduction. The surface layer of the cytoplasm of these cells contains various biochemical substances that are essential for their function.
Key Substance: Antifertilizin
- Antifertilizin is a specific chemical found in the cytoplasm of spermatozoa.
- Its primary role is to prevent premature fertilization, ensuring that sperm can survive long enough to reach the egg.
Other Options Explained
- Fertilizin: This is a substance associated with the egg that may help in the binding of sperm to the oocyte, but it is not found in spermatozoa.
- Agglutin: These are substances that can cause clumping of cells, often associated with immune responses but not specifically linked to sperm function.
- Hyaluronidase: While this enzyme is important in breaking down hyaluronic acid in the extracellular matrix, facilitating sperm penetration during fertilization, it is not a key component found specifically in the cytoplasm of sperm cells.
Conclusion
Antifertilizin serves as a protective factor for spermatozoa, highlighting its importance in reproductive biology. Understanding these substances is key for insights into fertility and reproductive health, making antifertilizin the correct answer in the context of the question.
