Answer 1

The correct option is B $\begin{array}{cccc}A-4& B-3& C-1& D-2\end{array}$

$\begin{array}{cc}\text{Column I}& \text{Column II}\\ \text{A. Head}& \text{4. Genetic material}\\ \text{B. Middle Piece}& \text{3. Energy}\\ \text{C. Acrosome}& \text{1. Enzymes}\\ \text{D. Tail}& \text{2. Sperm motility}\end{array}$

The sperm is 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 fertilization of the ovum. The middle piece has numerous mitochondria, which produce energy for the sperm movement. The tail facilitates sperm motility essential for fertilisation.
