Which among the following reaction is an example of a zero order reaction?

$\begin{aligned} \mathrm{C}_{12} \mathrm{H}_{22} \mathrm{O}_{11}(a q)+\mathrm{H}_2 \mathrm{O}(I) \longrightarrow & \mathrm{C}_6 \mathrm{H}_{12} \mathrm{O}_6(a q) \\ & +\mathrm{C}_6 \mathrm{H}_{22} \mathrm{O}_6(a q)\end{aligned}$

$2 \mathrm{NH}_3(\mathrm{g}) \xrightarrow{\mathrm{Pt}} \mathrm{N}_2(g)+3 \mathrm{H}_2$

$2 \mathrm{H}_2 \mathrm{O}_2(I) \longrightarrow 2 \mathrm{H}_2 \mathrm{O}(I)+\mathrm{O}_2(g)$

$\mathrm{H}_2(g)+\mathrm{I}_2(g) \longrightarrow 2 \mathrm{HI}(g)$
