The main idea here is that improved hydrogen peroxide is formulated with surfactants to boost cleaning and spreading on surfaces. Anionic and/or nonionic surfactants lower surface tension, helping the solution wet and spread more evenly, loosen and suspend soils, and improve contact with microbes. When soil is better removed and surfaces are more thoroughly wetted, the disinfecting action of hydrogen peroxide is more effective.

That’s why the option listing anionic and/or nonionic surfactants is the best choice. The other substances—glutaraldehyde, peracetic acid, and chlorine—are different disinfectants with their own active ingredients and aren’t described as components of this improved hydrogen peroxide formulation.
