Decomposition of hydrogen peroxide is retarded in the presence of :

The disintegration of the molecule into smaller components is a decomposition reaction. Water and dioxygen undergo highly reactive breakdowns when exposed to hydrogen peroxide. the following is the response:
$2{\mathrm{H}}_2{\mathrm{O}}_{2\left(\mathrm{l}\right)} \to 2{\mathrm{H}}_2{\mathrm{O}}_{\left(\mathrm{l}\right)}+ {\mathrm{O}}_{2\left(\mathrm{g}\right)}$
In the presence of metals, the process is catalysed. Thus, it is possible to rule out manganese dioxide and molybdenum. As the hydrogen peroxide is simultaneously oxidised and reduced, the hydrogen peroxide decomposition reaction is a disproportionation reaction.
Hydrogen peroxide is kept in wax-lined glass vials to stop the reaction. Glycerol and other alcohols are present in the wax. As a result, glycerin and alcohol might serve as unfavourable catalysts for the reaction that breaks down H2O2.

Hence, options A and D are the correct choices.
