Solution

The correct option is A Sodium silicate is formed
Silicon dioxide reacts as a weak acid with a strong base.

$S i O_{2}$ reacts with hot and concentrated sodium hydroxide to form sodium silicate ( $N a_{2} S i O_{3}$ ) and water.

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

So, the correct option is ( A )
