Q. What is $x$ in the following reaction?
$A l (s) + N a O H (a q) + H_{2} O (l) \to x + H_{2} (g)$

$N a_{2} [A l (O H)_{4}]^{-}$

$N a^{+} [A l (O H)_{4}^{-}$

$N a_{2} [A l (O H)_{6}]^{-}$

$N a^{+} [A l (O H)_{6}]^{-}$

$2 A l (s) + 2 N a O H (a q) + 6 H_{2} O (l) \to 2 N a^{+} [A l (O H)_{4}]^{-} (a q) + 3 H_{2} (g)$
