Solution

The correct option is D $S n$ and $Z n$
Amphoteric oxides can behave as an acid as well as the base. They react with both acids and bases to form salts. Tin oxide although doesn't dissolve in water but it is amphoteric in nature. Zinc oxide is also amphoteric in nature.

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

$S n O_{2} + H C l \to S n C l_{4} + H_{2} O$
$S n O_{2} + N a O H + H_{2} O \to N a_{2} [S n (O H)_{6}]$

Hence, option D is correct.
