Head of sperm contains

detailed solution

Correct option is A

Sperm is a microscopic structure composed of a head, neck, a middle piece, and a tail.

The sperm head contains an elongated haploid nucleus, the anterior portion of which is covered by a cap-like structure, acrosome. The acrosome is filled with enzymes that help in fertilisation of the ovum.

The middle section has a lot of mitochondria, which create energy for the tail movement. This helps sperm motility, which is important for fertilisation.
