Ammonia and red hot \( \mathrm{CuO} \) react to produce:
\( \mathrm{P} \)
(A) \( \mathrm{Cu}_{2} \mathrm{O}, \mathrm{N}_{2}, \mathrm{H}_{2} \)
(B) \( \mathrm{Cu}, \mathrm{H}_{2} \mathrm{O}, \mathrm{N}_{2} \)
(C) \( \mathrm{Cu}(\mathrm{OH})_{2}, \mathrm{~N}_{2} \)
(D) \( \left[\mathrm{Cu}\left(\mathrm{NH}_{3}\right) 4\right](\mathrm{OH})_{2} \)
