	Column I		Column II
A.	Head	(i)	Enzymes
B.	Middle piece	(ii)	Sperm motility
C.	Acrosome	(iii)	Energy
D.	Tail	(iv)	Genetic material

• A. $A-(ii),B-(iv),C-(i),D-(iii)$
• B. $A-(iv),B-(iii),C(i),D-(ii)$
• C. $A-(iv),B-(i),C-(ii),D-(iii)$
• D. $A-(ii),B-(i),C-(iii),D-(iv)$

Answer 1

Answer: (B)

The sperm can be divided into four parts:
(i) Head : consists of an elongated haploid nucleus storing genetic material and at tip of the head is acrosome, which consist of various hydrolysing enzymes.
(ii) Neck: It is very short and consists of two centrioles.
(iii) Middle piece : It is cylindrical in human sperm and consists of mitochondria, which provides energy for movement of sperm inside female reproductive tract. The energy provided by mitochondria can help sperm survive $1-2$ days.
(iv) Tail : It is long, slender and consists of cytoplasm. It helps in providing sperm with motility.
