The correct answer is "catalase in human tissues neutralizes it".
Hydrogen peroxide works to kill bacteria by forming free radicals which exerts oxidative stress in the bacterial cell leading mostly to cell membrane damage and lysis of the bacterial cells. In the environment of human tissues wherein there is catalase, hydrogen peroxide is converted to water and oxygen which has no antiseptic effect.
