O+NO
The oxidation numbers for nitrogen has been assigned.
+5

This is a reduction half equation. All atoms are balanced.
We balance charges by adding the appropriate number of electrons.
NO

O+NO
This is a balanced reduction half-reaction.
Thus, the number of electrons required to balance the equation is 3.
Hence, the correct option is C
