(D) $A.$ $Zn + 2NaOH 	ext{ (dil.)} \longrightarrow Na_2ZnO_2 + H_2(g)$ (Produces $H_2$ gas).$B.$ $NaH + H_2O \longrightarrow NaOH + H_2(g)$ (Produces $H_2$ gas).$C.$ $Na + (x+y)NH_3 \longrightarrow [Na(NH_3)_x]^+ + [e(NH_3)_y]^-$ (The ammoniated electron solution is unstable and slowly decomposes to produce $H_2$ gas).$D.$ $Cu + 	ext{dil. } H_2SO_4 \longrightarrow 	ext{No reaction}$. Since $Cu$ is below $H$ in the electrochemical series,it cannot displace $H_2$ from dilute acids.
