Quizplus · Accepted Answer

A stronger oxidizing agent is the one that has a higher positive reduction potential value. Among the options given, MnO is the only species with a positive reduction potential value (+1.51 V) compared to the negative reduction potential values of the other species. Thus, MnO is the strongest oxidizing agent among the given options.
