Correct Answer is : (NH2)2CO({NH}₂)₂{CO}(NH2​)2​CO

Elements	$\%$	Relative number of atoms	Simple Ratio
C	$20\%$	$\frac{20}{12}=1.66$	$\frac{1.66}{1.66}=1$
H	$6.67\%$	$\frac{6.67}{1}=6.67$	$\frac{6.67}{1.66}=4.16$
N	$46.67\%$	$\frac{46.67}{14}=3.33$	$\frac{3.33}{1.66}=2.02$
O	$26.64\%$	$\frac{26.64}{16}=1.66$	$\frac{1.66}{1.66}=1.0$
