(A) The concentration of NO will increase； the concentrations of N₂ and O₂ will decrease.
(B) The concentrations of N₂ and O₂ will increase； and the concentration of NO will decrease.
(C) The concentrations of N₂, O₂, and NO will increase.
(D) The concentrations of N₂, O₂, and NO will decrease.
(E) There will be no change in the concentrations of N₂, O₂, and NO.
