A couple has chosen to pay for the harvesting and storage of umbilical cord blood after the delivery of their child to secure a future source of embryonic stem cells. What is the most likely rationale for the couple's decision?
A) The stem cells may be able to produce a wide range of body cells.
B) The embryonic stem cells allow stable and permanent tissues to enter mitosis.
C) The stem cells can change the proliferative capacity of other cells.

Feedback:
Embryonic stem cells hold the potential for broad differentiation. They do not change the proliferative capacity of existing cells and they do not foster mitosis by removing CKIs.
