Among the following the total number of elements which produce H2 gas with NaOH is Zn, Al, Sn, Pb, P, S

Z n + 2 N a O H → N a 2 Z n O 2 + H 2 ↑ 2 A I + 2 N a O H + H 2 O → 2 N a A l O 2 + 3 H 2 ↑ S n + 2 N a O H + H 2 O → N a S n O 3 + 2 H 2 ↑ P 4 + 3 N a O H + 3 H 2 O → P H 3 ↑ + 3 N a H 2 P O 2

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

$\begin{array}{l} 2 A I + 2 N a O H + H_{2} O \to 2 N a A l O_{2} + 3 H_{2} ↑ \\ S n + 2 N a O H + H_{2} O \to N a S n O_{3} + 2 H_{2} ↑ \\ P_{4} + 3 N a O H + 3 H_{2} O \to P H_{3} ↑ + 3 N a H_{2} P O_{2} \end{array}$
