Which ordering of compounds is according to the decreasing order of the oxidation state of nitrogen?

$HNO_{3},NO,NH_{4}Cl,N_{2}$

$HNO_{3},NO,N_{2}, NH_{4}Cl$

$HNO_{3},NH_{4}Cl,NO,N_{2}$

$NO,HNO_{3},NH_{4}Cl,N_{2}$

Option B

Let oxidation number of "N" be x

In $HNO_{3}$ +1+x+3(-2)=0

$\Rightarrow$ x=+5

In $NO$ x-2=0 $\Rightarrow$ x=+2

in $N_{2}$ x=0

In $NH_{4}Cl$ x+4-1=0 $\Rightarrow$ x=-3
