Match List-I with List-II.

List-I	List-II
A. Head B. Middle piece C. Acrosome D. Tail	I. Enzymes II. Sperm motility III. Energy IV. Genetic material

Choose the correct answer from the options given below:

The correct option is A-IV, B-III, C-I, D-II.

Let us analyze the structure of a human sperm (spermatozoon) and match each part listed in List-I with its correct function or feature in List-II:

A. Head: The sperm head contains an elongated haploid nucleus. This nucleus carries the paternal genetic material (DNA) to be inherited by the offspring. Therefore, A matches with IV.

B. Middle piece: The middle piece of the sperm contains numerous mitochondria coiled around the axial filament. These mitochondria produce energy in the form of ATP, which powers the movement of the tail. Therefore, B matches with III.

C. Acrosome: The acrosome is a cap-like structure covering the anterior portion of the head. It is filled with hydrolytic enzymes (such as hyaluronidase and acrosin) that help the sperm penetrate the outer layers of the ovum during fertilization. Therefore, C matches with I.

D. Tail: The tail is a long, slender structure that performs lashing movements to facilitate sperm motility, enabling the sperm to swim towards the ovum. Therefore, D matches with II.

Matching the parts:
A → IV
B → III
C → I
D → II

This corresponds perfectly to the option: A-IV, B-III, C-I, D-II.
