The three main parts of sperm are indeed the head, mid-piece, and tail. The head contains the nucleus, which houses the genetic material, and is covered by an acrosome that contains enzymes essential for penetrating the egg during fertilization. The mid-piece is packed with mitochondria that provide the energy required for the sperm's movement, while the tail, or flagellum, is a long structure that propels the sperm forward through a whip-like motion.

Understanding this structure is crucial in the study of reproductive biology because each part of the sperm has a specific function that contributes to its overall role in fertilization. In comparison to the other answer choices, the inclusion of "mid-piece" correctly highlights the energy-providing region of the sperm, while none of the other options accurately name the components of sperm.
