(D) Pyridine $(C_5H_5N)$ has a hexagonal ring structure similar to benzene where one $CH$ group is replaced by a nitrogen atom.$1$. $\sigma$ bonds: There are $5$ $C-H$ bonds,$5$ $C-C/C-N$ single bonds,and $1$ $C-N$ double bond (which contains $1$ $\sigma$ bond). Total $\sigma$ bonds $= 5 + 5 + 1 = 11$.$2$. $\pi$ bonds: There are $3$ double bonds in the ring,each containing $1$ $\pi$ bond. Total $\pi$ bonds $= 3$.$3$. Lone pair of electrons: The nitrogen atom in pyridine has $1$ lone pair of electrons.Thus,the number of $\sigma$ bonds,$\pi$ bonds,and lone pairs are $11, 3, 1$ respectively.

Label	Order	Property
$i.$	$NH_3 > H_2O > SO_2$	Bond angle
$ii.$	$H_2O > NH_3 > H_2S$	Dipole moment
$iii.$	$N_2 > O_2 > H_2$	Bond enthalpy
$iv.$	$NO^{+} > O_2 > O_2^{2-}$	Bond order

The number of $\sigma$ bonds,$\pi$ bonds and lone pair of electrons in pyridine,respectively are:
