You are given the reaction cu + hno3 cu(no3)2 + no + h2o. which pair of half-reactions represents the balanced half-reactions for the reaction?

Oxidation reaction,Cu + HNO3 --> Cu(NO3)2

Reduction reaction, HNO3 --> NO + H2O

The reduction half reaction represents the balanced reaction as the number of Hydrogen on left side of reaction is equal to right side whereas, the nitrogen is also 1 in left side and 1 on right side

Look at the picture (it's the first option)
