The right answer is B.
Pluripotent cells are cells from a certain stage of development of the embryo, we no longer find totipotent cells, but what we commonly call embryonic stem cells which they can differentiate into cells of any tissue, but can not (by themselves) give birth to an entire fetus.
One of the interesting applications of multipotent stem cells lies in the treatment of genetic diseases.
The "multipotent" stem cells, they are more able to differentiate than in a limited number of cells having the same embryonic origin.
