Q. Choose the disproportionation reaction among the following redox reactions

$3 M g (s) + N_{2} (g) ⟶ M g_{3} N_{2} (s)$

$P_{4} (S) + 3 N a O H_{(a g)} + 3 H_{2} O (l) ⟶ P H_{3 (g)} + 3 N a H_{2} P O_{2} (a q)$

$C l_{2 (g)} + 2 K I (a q) ⟶ 2 K C l_{(a q)} + I_{2} (s)$

$C r_{2} O_{3 (s)} + 2 A l_{(s)} ⟶ A l_{2} O_{3 (s)} + 2 C r_{(s)}$

$2 N a H_{(s)} ⟶ 2 N a_{(s)} + H_{2 (g)}$

$P_{4 (S)} + 3 N a O H_{(a q)} + 3 H_{2 O (l)} ⟶ P H_{3 (g)} + 3 N a H_{2} P O_{2 (a q)}$
