Solution

The correct option is A $F_{2}$
$F_{2}$ is more electronegative than oxygen. Hence, only with fluorine, oxygen can be in $+ 2$ oxidation state.
$∴ X_{2}$ is $F_{2}$ .
The reaction of fluorine with cold and dilute alkali can be given as follow:
$2 F_{2} + 2 N a O H \to O F_{2} + 2 N a F + H_{2} O$
