Solution

The correct options are
A HF
C hot NaOH
Reaction with $H F$ :
$S i O_{2} + H F \to H_{2} [S i F_{6}] + H_{2} O$
Sodium hydroxide reacts with silicon dioxide to produce sodium silicate and water. This reaction takes place at a temperature of $900 - 1000 ° C$ .
$2 N a O H + S i O_{2} \to N a_{2} S i O_{3} + H_{2} O$
