Answer:
The answer is Atom.
Explanation:
The atom is the smallest constituent unit of matter that has the properties of a chemical element and that it is not possible to divide by chemical processes. The atom is formed by a nucleus with protons and neutrons and several orbital electrons (subatomic particles); whose number varies according to the chemical element. Atoms combine to form molecules that then interact to form solids, liquids and gases.
 
        
             
        
        
        
Answer;
C. Multipotent
Explanation;
-Multipotent cells are those cells that can develop into more than one cell type, however, they are more limited than pluripotent cells. Adult stem cells and cord blood stem cells are considered multipotent.
Totipotent cells on the other hand, are those cells that can form all the cell types in a body, together with the extraembryonic, or placental cells. Embryonic cells are the only cells that are totipotent within the first couple of cell divisions after fertilization. 
 Pluripotent cells are those cells that give rise to all of the cell types that make up the body; embryonic stem cells are considered pluripotent.
