Solution

The correct option is A $B e (O H)_{2}$
$B e (O H)_{2}$ is an amphoteric hydroxide.

With acids, $B e (O H)_{2}$ is neutralized giving salts,
$B e (O H)_{2} + 2 H C l \to B e C l_{2} + 2 H_{2} O$

$B e (O H)_{2}$ reacts with $N a O H$ also forming beryllate,
$B e (O H)_{2} + 2 N a O H \to N a_{2} B e O_{2} + 2 H_{2} O$
