Answer:
B. Multipotent cells
Explanation:
Multipotent stem cells are the one that develops from pluripotent stem cells during embryonic development. The multipotent stem cells are the stem cells which have specific functions. These cells develop into specific cell types to replace the older cells. 
For example, keratinocytes are the multipotent cells of the skin that produce new skin cells. Spermatogonia are the multipotent cells present in testes so that they can form sperms.

The correct answer that would best complete the given statement above would be A TWO-HEADED FLY. A high concentration of bicoid protein at the opposite ends of a developing drosophila embryo would result in the development of a two-headed fly. The bicoid <span>gene is a type of egg-polarity gene and is transcribed by nurse cells. </span>
