Answers

The correct answer is option C

Unipotent stem cells are those stem cells that can form cells of one lineage only. An adult would be having the maximum number of unipotent stem cell as it has gone through the process of cell differentiation and the cell have been differentiated into different kinds of cells.

An adult, since they are fully grown, they possess the most unipotent cells.
