 The acrosome is located at the anterior end of the sperm nucleus, not the posterior end.

The acrosome is a specialized structure present in the head of the sperm. It is a cap-like structure that covers the anterior part of the nucleus. It contains a variety of enzymes, including hyaluronidase and acrosin, which are involved in the process of fertilization.

Therefore, statement I is incorrect. Statement II, which states that the acrosome contains enzymes that help in the process of sperm entry into the ovum, is correct.

Option 4 is the correct answer.
