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.

The inner cellular layer of trophoblast that remains intact inside the blastocyst is termed Cytotrophoblast.
Cytotrophoblast is the inner layer of the trophoblast.
It is found on the outer side of the Blastocyst and inner side of the Syncytiotrophoblast.
Cytotrophoblast remains intact inside the blastocyst and is present as a inner cellular layer of trophoblast.
Cytotrophoblast produces several hormones like:
- GnRH
- Progesterone
- HCG
- Estrogen
Cytotrophoblast attaches the fetus that is growing to the uterine wall of the mother's body.
It plays an important role in embyro's transplantation.
Cytotrophoblast releases Proteinaceous enzymes between the endometrial cells allowing many finger-like projections.
