Which of the following can be used to prevent the decomposition of...

${H}_{2}{O}_{2}$ decomposes slowly on exposure to light.
$2{H}_{2}{O}_{2\left(l\right)} \to 2{H}_{2}{O}_{\left(l\right)} + {O}_{2\left(g\right)}$
In the presence of metal surfaces or traces of alkali (present in glass containers), the above reaction is catalysed. It is, therefore, stored in wax-lined glass or plastic vessels in dark. Urea can be added as a stabiliser. It is kept away from dust because dust can induce explosive decomposition of the compound. Urea act as negative catalysts in the decomposition of hydrogen peroxide.
