Concept - Those compounds which are more acidic than $\mathrm{H}_2 \mathrm{CO}_3$ can gives effervescence of $\mathrm{CO}_2$ with aq. $\mathrm{NaHCO}_3$.
Release $\mathrm{CO}_2 \uparrow$ gas with aq. NaHCO 3
$\Rightarrow[\text { A.S. }]_{\text {Comp. }} \gt [\text { A.S. }]_{\mathrm{H}_2 \mathrm{CO}_3}$
$\rightarrow$ Option 1,2 and 3 gives effervescence of $\mathrm{CO}_2$ gas with $\mathrm{NaHCO}_3$
$\rightarrow$ Option (4) Not gives $\mathrm{CO}_2$ gas with $\mathrm{NaHCO}_3$.
