Answer:
The correct answer would be adult stem cells.
Adult stem cells are self-renewal undifferentiated cells present in the human body. They are usually multipotent in nature, that is, they can differentiate into many different cell types but not all.
In contrast, embryonic stem cells are pluripotent stem cells, that is, they can differentiate into any cell type of the body.
Similarly, amniotic cells are also high potent stem cells.
Thus, adult stem cells are the most limited in differentiation.
