Solution

The correct option is C $Z n, S n$ and $A l$
The metals $Z n, S n$ and $A l$ will react with $N a O H$ and $K O H$ to Iibrate hydrogen gas. This is because these metals are amphoteric and can react with both bases and acids.

$2 A l + 2 N a O H + 2 H_{2} O \to 2 N a A l O_{2} + 3 H_{2}$

$S n + 2 N a O H + H_{2} O \to N a_{2} S n O_{3} + 2 H_{2}$
$Z n + 2 N a O H \to N a_{2} Z n O_{2} + H_{2}$
