Answer 2

(c) mitochondria.

In the middle piece of mammalian sperm, there are the mitochondria.

All of them can be numerous in number and are very well-developed.

A nucleus is present in the head of the sperm or the acrosome.

A centriole is there at the neck region of mammalian sperm.

A connecting piece, which is also called the neck region, connects the head to the long flagellum which is further divided into three distinct sections: the principal piece, the middle piece and the end piece.
