Which of the following compounds is $NOT$ acidic in nature?

$Na_2CO_3$ reacts with $SO_2$ in an alkaline medium to form:

$STATEMENT-1$: $Pb^{4+}$ compounds are stronger oxidizing agents than $Sn^{4+}$ compounds.
$STATEMENT-2$: The higher oxidation states for the group $14$ elements are more stable for the heavier members of the group due to 'inert pair effect'.

Silicon chloroform is prepared by

Carbon on reaction with hot conc. $H_2SO_4$ gives two oxides along with $H_2O$. What is the nature of these two oxides?

Given below are two statements,one is labelled as Assertion $A$ and the other is labelled as Reason $R$.
Assertion $A$: Carbon forms two important oxides $- CO$ and $CO_2$. $CO$ is neutral whereas $CO_2$ is acidic in nature.
Reason $R$: $CO_2$ can combine with water in a limited way to form carbonic acid,while $CO$ is sparingly soluble in water.
In the light of the above statements,choose the most appropriate answer from the options given below:
