The Production of Nitric Oxide Is Governed by the Reaction

The production of nitric oxide is governed by the reaction:
4 NH₃( g ) + 5 O₂( g ) → 4 NO( g ) + 6 H₂O( g )
If the rate at which NO is produced is 6.35 × 10 ⁻² mol L ^{− 1}s ^{− 1}, at what rate is O₂ consumed?

A) 8.29 × 10 ^{− 3} mol L ^{− 1}s ^{− 1}
B) 1.59 × 10 ^{− 2} mol L ^{− 1}s ^{− 1}
C) 6.35 × 10 ⁻² mol L ^{− 1}s ^{− 1}
D) 7.94 × 10 ⁻² mol L ^{− 1}s ^{− 1}
