Solution

The correct option is A Nucleus
The primary sex organ, the testis in males produce gametes i.e. sperms. Mature sperm cell consists of a head, a neck, a middle piece and a tail. A plasma membrane envelops the whole body of sperm. The sperm head contains a very little cytoplasm, 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 fertilization of ovum.
Thus, the correct answer is 'Nucleus'.
