Dear student 
Let oxidation number of nitrogen=x
Oxidation number of hydrogen =+1
Oxidation number of oxygen=−2
1+x+3×(−2)=0
⇒x=+5
C is correct option 
Good Luck

Let x be the oxidation number of N in nitric acid. 
The oxidation numbers of H and O in nitric acid are +1 and −2 respectively. The sum of the oxidation numbers is zero for the neutral molecule. 
Hence, 1+x+3(2−)=0 
or, x=5
